Which variable represents displacement?
If a velocity increases from 0 to 20 m/s in 10 s, what is the average acceleration?
- 0.5 m/s2
- 2 m/s2
- 10 m/s2
- 30 m/s2
3.2 Representing Acceleration with Equations and Graphs
For the motion of a falling object, which graphs are straight lines?
- Acceleration versus time only
- Displacement versus time only
- Displacement versus time and acceleration versus time
- Velocity versus time and acceleration versus time
A bullet in a gun is accelerated from the firing chamber to the end of the barrel at an average rate of 6.30×105 m/s2 for 8.10×10−4 s. What is the bullet’s final velocity when it leaves the barrel, commonly known as the muzzle velocity?
- 7.79 m/s
- 51.0 m/s
- 510 m/s
- 1020 m/s
