1. A rocket is launched in the air and its height, in feet, is modeled by the function $h$.

Here is a graph representing $h$.

Select three true statements about the situation.

1. The rocket is launched from a height less than 20 feet above the ground.
2. The rocket is launched from about 20 feet above the ground.
3. The rocket reaches its maximum height after about 3 seconds.
4. The rocket reaches its maximum height after about 160 seconds.
5. The maximum height of the rocket is about 160 feet.

1. How many meters $(d$) did the baseball travel in 0 seconds ($t$)?

2. How many meters $(d$) did the baseball travel in 0.5 seconds ($t$)?

3. How many meters ($d$) did the baseball travel in 1 second ($t$)?

4. How many meters ($d$) did the baseball travel in 1.5 seconds ($t$)?

5. How many meters ($d$) did the baseball travel in 2 seconds ($t$)?

6. Is this graph an accurate representation of the data in the table? 
   
   
   
   

7. Is the baseball traveling at a constant speed?

3. A small ball is dropped from a 100-foot-tall building. Which equation could represent the ball’s height, $h(t)$, in feet, relative to the ground, as a function of time, $t$, in seconds?
