# Question: A tennis ball is dropped from a height of 10 0

A tennis ball is dropped from a height of 10.0 m. It rebounds off the floor and comes up to a height of only 4.00 m on its first rebound. (Ignore the small amount of time the ball is in contact with the floor.)

(a) Determine the ball’s speed just before it hits the floor on the way down.

(b) Determine the ball’s speed as it leaves the floor on its way up to its first rebound height.

(c) How long is the ball in the air from the time it is dropped until the time it reaches its maximum height on the first rebound?
