Question

A soft tennis ball is dropped onto a hard floor from a height of 1.90 m and rebounds to a height of 1.49 m. (Assume that the positive direction is upward.)

(a) Calculate its velocity just before it strikes the floor.
m/s
(b) Calculate its velocity just after it leaves the floor on its way back up.
m/s
(c) Calculate its acceleration during contact with the floor if that contact lasts 3.50 ms.
m/s2
(d) How much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid?
m

Step 1

Since we only answer up to 3 sub-parts, we will answer the first 3. Please resubmit the question and specify the other subparts (up to 3) you would like answered.

Step 2

Given:

Initial height from which the soft tennis ball is dropped is, h = 1.90 m

The height to which the ball rebounces is, h'=1.49 m

Step 3

Part a

We need to calculate the velocity of the ball just before it strikes.

The ball would free fall under gravity.
