Problem 28P

A 200 g ball is dropped from a height of 2.0 m, bounces on a hard floor, and rebounds to a height of 1.5 m. Figure P9.41 shows the impulse received from the floor. What maximum force does the floor exert on the ball?

Step-by-Step Solution:

Solution 28 P

Step 1 of 3</p>

We have to find the maximum force the floor exerts on the ball.

The motion diagram for the problem is as shown in the below figure.

Known:

m

To find:

and

Step 2 of 3</p>

The velocity of the ball just before and after it hits the floor can be found from the kinematic equation for constant acceleration.
