5. A soup bowl falls off of a table. It takes 0.4 sec to hit the ground. How high was the table?

6. A golf ball and a baseball are dropped at the same time. In the absence of air resistance, which ball has the greater acceleration?

7. Why isPhysics the most basic science?

8. An apple tossed vertically upward rises, reaches its highest point, and then falls back to its starting point. During this time, the direction of the acceleration of the apple is always ___ and directed ______.

9. Nine seconds after starting from rest, a car is moving at 45 m/s. What is the car’s average acceleration?

10. You take a trip that covers 600 km in 8 hours. What was your average speed?

11. A ball is thrown straight up. At the top of its path, its acceleration is ___.

12.How are the horizontal component of a projectile’s velocity and the vertical component of the velocity related?

13. When you look at the speedometer in a moving car, you can see the car’s______speed.
