Part 1 – A Ball Thrown Straight Up

1) At what time does the ball reach its greatest height?

2) What is the maximum height?

3) What is the velocity at t = 0 seconds?

4) What is the velocity at t = 6 seconds?

5) At what time is the velocity equal to zero?

6) At that moment (v = 0), what is the ball doing?

7) Complete the sentence: “At maximum height, the velocity is ____.”

8) What is the acceleration (constant) during the whole flight?

9) Is acceleration ever zero during the flight? (yes/no)

10) What is the cannonball’s initial vertical velocity?

11) What is the maximum height reached?

12) When does it stop rising (vertical v = 0)?

13) Compared to the straight-up throw, the cannonball’s vertical motion is…

14) What is the total time in the air?

15) Suppose the cannon ball moves horizontally at a constant speed of:
