3.4 Motion with Constant Acceleration

University Physics Volume 13.4 Motion with Constant Acceleration

Learning Objectives

By the end of this section, you will be able to:

  • Identify which equations of motion are to be used to solve for unknowns.
  • Use appropriate equations of motion to solve a two-body pursuit problem.

You might guess that the greater the acceleration of, say, a car moving away from a stop sign, the greater the car’s displacement in a given time. But, we have not developed a specific equation that relates acceleration and displacement. In this section, we look at some convenient equations for kinematic relationships, starting from the definitions of displacement, velocity, and acceleration. We first investigate a single object in motion, called single-body motion. Then we investigate the motion of two objects, called two-body pursuit problems.

Notation

First, let us make some simplifications in notation. Taking the initial time to be zero, as if time is measured with a stopwatch, is a great simplification. Since elapsed time is Δt=tft0Δt=tft0, taking t0=0t0=0 means thatΔt=tfΔt=tf, the final time on the stopwatch. When initial time is taken to be zero, we use the subscript 0 to denote initial values of position and velocity. That is, x0x0 is the initial position and v0v0 is the initial velocity. We put no subscripts on the final values. That is, t is the final time, x is the final position, and v is the final velocity. This gives a simpler expression for elapsed time, Δt=tΔt=t. It also simplifies the expression for x displacement, which is now Δx=xx0Δx=xx0. Also, it simplifies the expression for change in velocity, which is now Δv=vv0Δv=vv0. To summarize, using the simplified notation, with the initial time taken to be zero,

Δt=tΔx=xx0Δv=vv0,Δt=tΔx=xx0Δv=vv0,

where the subscript 0 denotes an initial value and the absence of a subscript denotes a final value in whatever motion is under consideration.

We now make the important assumption that acceleration is constant. This assumption allows us to avoid using calculus to find instantaneous acceleration. Since acceleration is constant, the average and instantaneous accelerations are equal—that is,

a=a=constant.a=a=constant.

Thus, we can use the symbol a for acceleration at all times. Assuming acceleration to be constant does not seriously limit the situations we can study nor does it degrade the accuracy of our treatment. For one thing, acceleration is constant in a great number of situations. Furthermore, in many other situations we can describe motion accurately by assuming a constant acceleration equal to the average acceleration for that motion. Lastly, for motion during which acceleration changes drastically, such as a car accelerating to top speed and then braking to a stop, motion can be considered in separate parts, each of which has its own constant acceleration.

Displacement and Position from Velocity

To get our first two equations, we start with the definition of average velocity:

v=ΔxΔt.v=ΔxΔt.

Substituting the simplified notation for ΔxΔx and ΔtΔt yields

v=xx0t.v=xx0t.

Solving for x gives us

x=x0+vt,x=x0+vt,
3.10

where the average velocity is

v=v0+v2.v=v0+v2.
3.11

The equation v=v0+v2v=v0+v2 reflects the fact that when acceleration is constant, vv is just the simple average of the initial and final velocities. Figure 3.18 illustrates this concept graphically. In part (a) of the figure, acceleration is constant, with velocity increasing at a constant rate. The average velocity during the 1-h interval from 40 km/h to 80 km/h is 60 km/h:

v=v0+v2=40km/h+80km/h2=60km/h.v=v0+v2=40km/h+80km/h2=60km/h.

In part (b), acceleration is not constant. During the 1-h interval, velocity is closer to 80 km/h than 40 km/h. Thus, the average velocity is greater than in part (a).

Graph A shows velocity in kilometers per hour plotted versus time in hour. Velocity increases linearly from 40 kilometers per hour at 1 hour, point vo, to 80 kilometers per hour at 2 hours, point v. Graph B shows velocity in kilometers per hour plotted versus time in hour. Velocity increases from 40 kilometers per hour at 1 hour, point vo, to 80 kilometers per hour at 2 hours, point v. Increase is not linear – first velocity increases very fast, then increase slows down.
Figure 3.18 (a) Velocity-versus-time graph with constant acceleration showing the initial and final velocities v0andvv0andv. The average velocity is 12(v0+v)=60 km/h12(v0+v)=60 km/h. (b) Velocity-versus-time graph with an acceleration that changes with time. The average velocity is not given by 12(v0+v)12(v0+v), but is greater than 60 km/h.

Solving for Final Velocity from Acceleration and Time

We can derive another useful equation by manipulating the definition of acceleration:

a=ΔvΔt.a=ΔvΔt.

Substituting the simplified notation for ΔvΔv and ΔtΔt gives us

a=vv0t(constanta).a=vv0t(constanta).

Solving for v yields

v=v0+at(constanta).v=v0+at(constanta).
3.12

Example 3.7

Calculating Final Velocity

An airplane lands with an initial velocity of 70.0 m/s and then accelerates opposite to the motion at 1.50 m/s2 for 40.0 s. What is its final velocity?

Strategy

First, we identify the knowns: v0=70m/s,a=−1.50m/s2,t=40sv0=70m/s,a=−1.50m/s2,t=40s.

Second, we identify the unknown; in this case, it is final velocity vfvf.

Last, we determine which equation to use. To do this we figure out which kinematic equation gives the unknown in terms of the knowns. We calculate the final velocity using Equation 3.12, v=v0+atv=v0+at.

Solution

Substitute the known values and solve:
v=v0+at=70.0m/s+(−1.50m/s2)(40.0 s)=10.0 m/s.v=v0+at=70.0m/s+(−1.50m/s2)(40.0 s)=10.0 m/s.

Figure 3.19 is a sketch that shows the acceleration and velocity vectors.

Figure shows airplane at two different time periods. At t equal zero seconds it has velocity of 70 meters per second and acceleration of -1.5 meters per second squared. At t equal 40 seconds it has velocity of 10 meters per second and acceleration of -1.5 meters per second squared.
Figure 3.19 The airplane lands with an initial velocity of 70.0 m/s and slows to a final velocity of 10.0 m/s before heading for the terminal. Note the acceleration is negative because its direction is opposite to its velocity, which is positive.

Significance

The final velocity is much less than the initial velocity, as desired when slowing down, but is still positive (see figure). With jet engines, reverse thrust can be maintained long enough to stop the plane and start moving it backward, which is indicated by a negative final velocity, but is not the case here.

In addition to being useful in problem solving, the equation v=v0+atv=v0+at gives us insight into the relationships among velocity, acceleration, and time. We can see, for example, that

  • Final velocity depends on how large the acceleration is and how long it lasts
  • If the acceleration is zero, then the final velocity equals the initial velocity (v = v0), as expected (in other words, velocity is constant)
  • If a is negative, then the final velocity is less than the initial velocity

All these observations fit our intuition. Note that it is always useful to examine basic equations in light of our intuition and experience to check that they do indeed describe nature accurately.

Solving for Final Position with Constant Acceleration

We can combine the previous equations to find a third equation that allows us to calculate the final position of an object experiencing constant acceleration. We start with

v=v0+at.v=v0+at.

Adding v0v0 to each side of this equation and dividing by 2 gives

v0+v2=v0+12at.v0+v2=v0+12at.

Since v0+v2=vv0+v2=v for constant acceleration, we have

v=v0+12at.v=v0+12at.

Now we substitute this expression for vv into the equation for displacement, x=x0+vtx=x0+vt, yielding

x=x0+v0t+12at2(constanta).x=x0+v0t+12at2(constanta).
3.13

Example 3.8

Calculating Displacement of an Accelerating Object

Dragsters can achieve an average acceleration of 26.0 m/s2. Suppose a dragster accelerates from rest at this rate for 5.56 s Figure 3.20. How far does it travel in this time?
Picture shows a race car with smoke coming off of its back tires.
Figure 3.20 U.S. Army Top Fuel pilot Tony “The Sarge” Schumacher begins a race with a controlled burnout. (credit: Lt. Col. William Thurmond. Photo Courtesy of U.S. Army.)

Strategy

First, let’s draw a sketch Figure 3.21. We are asked to find displacement, which is x if we take x0x0 to be zero. (Think about x0x0 as the starting line of a race. It can be anywhere, but we call it zero and measure all other positions relative to it.) We can use the equation x=x0+v0t+12at2x=x0+v0t+12at2 when we identify v0v0, aa, and t from the statement of the problem.
Figure shows race car with acceleration of 26 meters per second squared.
Figure 3.21 Sketch of an accelerating dragster.

Solution

First, we need to identify the knowns. Starting from rest means that v0=0v0=0, a is given as 26.0 m/s2 and t is given as 5.56 s.

Second, we substitute the known values into the equation to solve for the unknown:

x=x0+v0t+12at2.x=x0+v0t+12at2.

Since the initial position and velocity are both zero, this equation simplifies to

x=12at2.x=12at2.

Substituting the identified values of a and t gives

x=12(26.0m/s2)(5.56s)2=402m.x=12(26.0m/s2)(5.56s)2=402m.

Significance

If we convert 402 m to miles, we find that the distance covered is very close to one-quarter of a mile, the standard distance for drag racing. So, our answer is reasonable. This is an impressive displacement to cover in only 5.56 s, but top-notch dragsters can do a quarter mile in even less time than this. If the dragster were given an initial velocity, this would add another term to the distance equation. If the same acceleration and time are used in the equation, the distance covered would be much greater.

What else can we learn by examining the equation x=x0+v0t+12at2?x=x0+v0t+12at2? We can see the following relationships:

  • Displacement depends on the square of the elapsed time when acceleration is not zero. In Example 3.8, the dragster covers only one-fourth of the total distance in the first half of the elapsed time.
  • If acceleration is zero, then initial velocity equals average velocity (v0=v)(v0=v), and x=x0+v0t+12at2becomesx=x0+v0t.x=x0+v0t+12at2becomesx=x0+v0t.

Solving for Final Velocity from Distance and Acceleration

A fourth useful equation can be obtained from another algebraic manipulation of previous equations. If we solve v=v0+atv=v0+at for t, we get

t=vv0a.t=vv0a.

Substituting this and v=v0+v2v=v0+v2 into x=x0+vtx=x0+vt, we get

v2=v02+2a(xx0)(constanta).v2=v02+2a(xx0)(constanta).
3.14

Example 3.9

Calculating Final Velocity

Calculate the final velocity of the dragster in Example 3.8 without using information about time.

Strategy

The equation v2=v02+2a(xx0)v2=v02+2a(xx0) is ideally suited to this task because it relates velocities, acceleration, and displacement, and no time information is required.

Solution

First, we identify the known values. We know that v0 = 0, since the dragster starts from rest. We also know that xx0 = 402 m (this was the answer in Example 3.8). The average acceleration was given by a = 26.0 m/s2.

Second, we substitute the knowns into the equation v2=v02+2a(xx0)v2=v02+2a(xx0) and solve for v:

v2=0+2(26.0m/s2)(402m).v2=0+2(26.0m/s2)(402m).

Thus,

v2=2.09×104m2/s2v=2.09×104m2/s2=145m/s.v2=2.09×104m2/s2v=2.09×104m2/s2=145m/s.

Significance

A velocity of 145 m/s is about 522 km/h, or about 324 mi/h, but even this breakneck speed is short of the record for the quarter mile. Also, note that a square root has two values; we took the positive value to indicate a velocity in the same direction as the acceleration.

An examination of the equation v2=v02+2a(xx0)v2=v02+2a(xx0) can produce additional insights into the general relationships among physical quantities:

  • The final velocity depends on how large the acceleration is and the distance over which it acts.
  • For a fixed acceleration, a car that is going twice as fast doesn’t simply stop in twice the distance. It takes much farther to stop. (This is why we have reduced speed zones near schools.)

Putting Equations Together

In the following examples, we continue to explore one-dimensional motion, but in situations requiring slightly more algebraic manipulation. The examples also give insight into problem-solving techniques. The note that follows is provided for easy reference to the equations needed. Be aware that these equations are not independent. In many situations we have two unknowns and need two equations from the set to solve for the unknowns. We need as many equations as there are unknowns to solve a given situation.

Summary of Kinematic Equations (constant a)

x=x0+vtx=x0+vt
v=v0+v2v=v0+v2
v=v0+atv=v0+at
x=x0+v0t+12at2x=x0+v0t+12at2
v2=v02+2a(xx0)v2=v02+2a(xx0)

Before we get into the examples, let’s look at some of the equations more closely to see the behavior of acceleration at extreme values. Rearranging Equation 3.12, we have

a=vv0t.a=vv0t.

From this we see that, for a finite time, if the difference between the initial and final velocities is small, the acceleration is small, approaching zero in the limit that the initial and final velocities are equal. On the contrary, in the limit t0t0 for a finite difference between the initial and final velocities, acceleration becomes infinite.

Similarly, rearranging Equation 3.14, we can express acceleration in terms of velocities and displacement:

a=v2v022(xx0).a=v2v022(xx0).

Thus, for a finite difference between the initial and final velocities acceleration becomes infinite in the limit the displacement approaches zero. Acceleration approaches zero in the limit the difference in initial and final velocities approaches zero for a finite displacement.

Example 3.10

How Far Does a Car Go?

On dry concrete, a car can accelerate opposite to the motion at a rate of 7.00 m/s2, whereas on wet concrete it can accelerate opposite to the motion at only 5.00 m/s2. Find the distances necessary to stop a car moving at 30.0 m/s (about 110 km/h) on (a) dry concrete and (b) wet concrete. (c) Repeat both calculations and find the displacement from the point where the driver sees a traffic light turn red, taking into account their reaction time of 0.500 s to get their foot on the brake.

Strategy

First, we need to draw a sketch Figure 3.22. To determine which equations are best to use, we need to list all the known values and identify exactly what we need to solve for.
Figure shows motor vehicle that moved with the speed of 30 meters per second. A stop light is located at the unknown distance delta x from the motor vehicle. Speed of motor vehicle is zero meters per second when it reaches stop light.
Figure 3.22 Sample sketch to visualize acceleration opposite to the motion and stopping distance of a car.

Solution

  1. First, we need to identify the knowns and what we want to solve for. We know that v0 = 30.0 m/s, v = 0, and a = −7.00 m/s2 (a is negative because it is in a direction opposite to velocity). We take x0 to be zero. We are looking for displacement ΔxΔx, or xx0.
    Second, we identify the equation that will help us solve the problem. The best equation to use is
    v2=v02+2a(xx0).v2=v02+2a(xx0).
    This equation is best because it includes only one unknown, x. We know the values of all the other variables in this equation. (Other equations would allow us to solve for x, but they require us to know the stopping time, t, which we do not know. We could use them, but it would entail additional calculations.)
    Third, we rearrange the equation to solve for x:
    xx0=v2v022axx0=v2v022a
    and substitute the known values:
    x0=02(30.0m/s)22(−7.00m/s2).x0=02(30.0m/s)22(−7.00m/s2).
    Thus,
    x=64.3m on dry concrete.x=64.3m on dry concrete.
  2. This part can be solved in exactly the same manner as (a). The only difference is that the acceleration is −5.00 m/s2. The result is
    xwet=90.0m on wet concrete.xwet=90.0m on wet concrete.
  3. When the driver reacts, the stopping distance is the same as it is in (a) and (b) for dry and wet concrete. So, to answer this question, we need to calculate how far the car travels during the reaction time, and then add that to the stopping time. It is reasonable to assume the velocity remains constant during the driver’s reaction time.
    To do this, we, again, identify the knowns and what we want to solve for. We know that v=30.0m/sv=30.0m/s, treaction=0.500streaction=0.500s, and areaction=0areaction=0. We take x0-reactionx0-reaction to be zero. We are looking for xreactionxreaction.
    Second, as before, we identify the best equation to use. In this case, x=x0+vtx=x0+vt works well because the only unknown value is x, which is what we want to solve for.
    Third, we substitute the knowns to solve the equation:
    x=0+(30.0m/s)(0.500s)=15.0m.x=0+(30.0m/s)(0.500s)=15.0m.
    This means the car travels 15.0 m while the driver reacts, making the total displacements in the two cases of dry and wet concrete 15.0 m greater than if he reacted instantly.
    Last, we then add the displacement during the reaction time to the displacement when braking (Figure 3.23),
    xbraking+xreaction=xtotal,xbraking+xreaction=xtotal,
    and find (a) to be 64.3 m + 15.0 m = 79.3 m when dry and (b) to be 90.0 m + 15.0 m = 105 m when wet.
Top figure shows cars located at 64.3 meters and 90 meters from the starting point for dry and wet conditions, respectively. Bottom figure shows cars located at 79.3 meters and 105 meters from the starting point for dry and wet conditions, respectively.
Figure 3.23 The distance necessary to stop a car varies greatly, depending on road conditions and driver reaction time. Shown here are the braking distances for dry and wet pavement, as calculated in this example, for a car traveling initially at 30.0 m/s. Also shown are the total distances traveled from the point when the driver first sees a light turn red, assuming a 0.500-s reaction time.

Significance

The displacements found in this example seem reasonable for stopping a fast-moving car. It should take longer to stop a car on wet pavement than dry. It is interesting that reaction time adds significantly to the displacements, but more important is the general approach to solving problems. We identify the knowns and the quantities to be determined, then find an appropriate equation. If there is more than one unknown, we need as many independent equations as there are unknowns to solve. There is often more than one way to solve a problem. The various parts of this example can, in fact, be solved by other methods, but the solutions presented here are the shortest.

Example 3.11

Calculating Time

Suppose a car merges into freeway traffic on a 200-m-long ramp. If its initial velocity is 10.0 m/s and it accelerates at 2.00 m/s2, how long does it take the car to travel the 200 m up the ramp? (Such information might be useful to a traffic engineer.)

Strategy

First, we draw a sketch Figure 3.24. We are asked to solve for time t. As before, we identify the known quantities to choose a convenient physical relationship (that is, an equation with one unknown, t.)
Figure shows car accelerating from the speed of 10 meters per second at a rate of 2 meters per second squared. Acceleration distance is 200 meters.
Figure 3.24 Sketch of a car accelerating on a freeway ramp.

Solution

Again, we identify the knowns and what we want to solve for. We know that x0=0,x0=0,
v0=10m/s,a=2.00m/s2v0=10m/s,a=2.00m/s2, and x = 200 m.

We need to solve for t. The equation x=x0+v0t+12at2x=x0+v0t+12at2 works best because the only unknown in the equation is the variable t, for which we need to solve. From this insight we see that when we input the knowns into the equation, we end up with a quadratic equation.

We need to rearrange the equation to solve for t, then substituting the knowns into the equation:

200m=0m+(10.0m/s)t+12(2.00m/s2)t2.200m=0m+(10.0m/s)t+12(2.00m/s2)t2.

We then simplify the equation. The units of meters cancel because they are in each term. We can get the units of seconds to cancel by taking t = t s, where t is the magnitude of time and s is the unit. Doing so leaves

200=10t+t2.200=10t+t2.

We then use the quadratic formula to solve for t,

t2+10t200=0t=b±b24ac2a,t2+10t200=0t=b±b24ac2a,

which yields two solutions: t = 10.0 and t = −20.0. A negative value for time is unreasonable, since it would mean the event happened 20 s before the motion began. We can discard that solution. Thus,

t=10.0s.t=10.0s.

Significance

Whenever an equation contains an unknown squared, there are two solutions. In some problems both solutions are meaningful; in others, only one solution is reasonable. The 10.0-s answer seems reasonable for a typical freeway on-ramp.

A rocket accelerates at a rate of 20 m/s2 during launch. How long does it take the rocket to reach a velocity of 400 m/s?

Example 3.12

Acceleration of a Spaceship

A spaceship has left Earth’s orbit and is on its way to the Moon. It accelerates at 20 m/s2 for 2 min and covers a distance of 1000 km. What are the initial and final velocities of the spaceship?

Strategy

We are asked to find the initial and final velocities of the spaceship. Looking at the kinematic equations, we see that one equation will not give the answer. We must use one kinematic equation to solve for one of the velocities and substitute it into another kinematic equation to get the second velocity. Thus, we solve two of the kinematic equations simultaneously.

Solution

First we solve for v0v0 using x=x0+v0t+12at2:x=x0+v0t+12at2:
xx0=v0t+12at2xx0=v0t+12at2
1.0×106m=v0(120.0s)+12(20.0m/s2)(120.0s)21.0×106m=v0(120.0s)+12(20.0m/s2)(120.0s)2
v0=7133.3m/s.v0=7133.3m/s.

Then we substitute v0v0 into v=v0+atv=v0+at to solve for the final velocity:

v=v0+at=7133.3m/s+(20.0m/s2)(120.0s)=9533.3m/s.v=v0+at=7133.3m/s+(20.0m/s2)(120.0s)=9533.3m/s.

Significance

There are six variables in displacement, time, velocity, and acceleration that describe motion in one dimension. The initial conditions of a given problem can be many combinations of these variables. Because of this diversity, solutions may not be as easy as simple substitutions into one of the equations. This example illustrates that solutions to kinematics may require solving two simultaneous kinematic equations.

With the basics of kinematics established, we can go on to many other interesting examples and applications. In the process of developing kinematics, we have also glimpsed a general approach to problem solving that produces both correct answers and insights into physical relationships. The next level of complexity in our kinematics problems involves the motion of two interrelated bodies, called two-body pursuit problems.

Two-Body Pursuit Problems

Up until this point we have looked at examples of motion involving a single body. Even for the problem with two cars and the stopping distances on wet and dry roads, we divided this problem into two separate problems to find the answers. In a two-body pursuit problem, the motions of the objects are coupled—meaning, the unknown we seek depends on the motion of both objects. To solve these problems we write the equations of motion for each object and then solve them simultaneously to find the unknown. This is illustrated in Figure 3.25.

Left figure shows red car accelerating towards the blue car. Right figure shows red car catching blue car.
Figure 3.25 A two-body pursuit scenario where car 2 has a constant velocity and car 1 is behind with a constant acceleration. Car 1 catches up with car 2 at a later time.

The time and distance required for car 1 to catch car 2 depends on the initial distance car 1 is from car 2 as well as the velocities of both cars and the acceleration of car 1. The kinematic equations describing the motion of both cars must be solved to find these unknowns.

Consider the following example.

Example 3.13

Cheetah Catching a Gazelle

A cheetah waits in hiding behind a bush. The cheetah spots a gazelle running past at 10 m/s. At the instant the gazelle passes the cheetah, the cheetah accelerates from rest at 4 m/s2 to catch the gazelle. (a) How long does it take the cheetah to catch the gazelle? (b) What is the displacement of the gazelle and cheetah?

Strategy

We use the set of equations for constant acceleration to solve this problem. Since there are two objects in motion, we have separate equations of motion describing each animal. But what links the equations is a common parameter that has the same value for each animal. If we look at the problem closely, it is clear the common parameter to each animal is their position x at a later time t. Since they both start at x0=0x0=0, their displacements are the same at a later time t, when the cheetah catches up with the gazelle. If we pick the equation of motion that solves for the displacement for each animal, we can then set the equations equal to each other and solve for the unknown, which is time.

Solution

  1. Equation for the gazelle: The gazelle has a constant velocity, which is its average velocity, since it is not accelerating. Therefore, we use Equation 3.10 with x0=0x0=0:
    x=x0+vt=vt.x=x0+vt=vt.
    Equation for the cheetah: The cheetah is accelerating from rest, so we use Equation 3.13 with x0=0x0=0 and v0=0v0=0:
    x=x0+v0t+12at2=12at2.x=x0+v0t+12at2=12at2.
    Now we have an equation of motion for each animal with a common parameter, which can be eliminated to find the solution. In this case, we solve for t:
    x=vt=12at2t=2va.x=vt=12at2t=2va.
    The gazelle has a constant velocity of 10 m/s, which is its average velocity. The acceleration of the cheetah is 4 m/s2. Evaluating t, the time for the cheetah to reach the gazelle, we have
    t=2va=2(10 m/s)4m/s2=5s.t=2va=2(10 m/s)4m/s2=5s.
  2. To get the displacement, we use either the equation of motion for the cheetah or the gazelle, since they should both give the same answer.
    Displacement of the cheetah:
    x=12at2=12(4m/s2)(5)2=50m.x=12at2=12(4m/s2)(5)2=50m.
    Displacement of the gazelle:
    x=vt=10 m/s(5)=50m.x=vt=10 m/s(5)=50m.
    We see that both displacements are equal, as expected.

Significance

It is important to analyze the motion of each object and to use the appropriate kinematic equations to describe the individual motion. It is also important to have a good visual perspective of the two-body pursuit problem to see the common parameter that links the motion of both objects.
