10. Kinematic Problems
The value of acceleration due to gravity (g) on the moon is 1.63 m/s2 .
(a) Would a ball that is dropped by an astronaut hit the surface of the Moon with a greater, equal or lesser speed than that of a ball dropped from the same height to earth?
(b) Would it take the ball more, less or equal time to fall?

11. Kinematic Problems
A car with a velocity of 22 m/s is accelerated uniformly at the rate of 1.6 m/s2 for 6.8 seconds. What is the final velocity of the car?

12. Kinematic Problems
Determine the displacement of a plane that experiences uniform acceleration from 66.0 m/s to 88 m/s in 12 seconds.

13. Kinematic Problems
You throw a ball downward from a window at a speed of 2.0 m/s. How fast will it be moving when it hits the sidewalk 2.5 m below?
If your throw the ball in problem #4 up instead of down, how fast will it be moving when it hits the sidewalk?
