1. A baseball is tossed straight up into the air at 3 m/s.

a. What is the maximum height the ball will reach?

b. What is the hang time of the ball?

c. How fast is the ball moving when it returns to the person’s hand?

2. An object had an average speed of 80 m/s. Its final speed was 120 m/s. What was its initial speed?

3. A person gets in their car and begins accelerating from rest at a rate of 6.0 m/s2. Below, chart the distance the car has travelled for each of the first four seconds. Show the work you used to get each distance. Graph your information.

The speed vs time graph above shows 10 seconds in the motion of an object. Use this graph to answer the questions that follow.

1) What is the slope of the line?

2) What does the slope of the line represent?

3) Give the equation of the line?

4) What distance will the object travel during this 10 s? Show your work.

5) What will the objects speed be after 25 s? Show your work.
