Chapter 11: Q. 13 (page 287)

A $250 g$ ball collides with a wall. FIGURE EX11.13 shows the ball’s velocity and the force exerted on the ball by the wall. What is $v_{f x}$ , the ball’s rebound velocity?

Short Answer

Expert verified

The rebound velocity of ball $6 m / s$ .

Step by step solution

Given information

We need to find the rebound velocity of ball.

Simplify

By using the impulse-momentum theorem, we can assume collisions are elastic. Initial velocitiy $v_{i x} = - 10 m / s$ showm in figure left and in the right figure $J_{x} = (500 N \times 0.008 s) = 4 N s$

So we have

$p_{f x} = p_{i x} + J_{x} m v_{f x} = m v_{i x} + J_{x} / : m v_{f x} = v_{i x} + \frac{J_{x}}{m} = - 10 m / s + \frac{4 N s}{0.250 k g} = 6 m / s .$
