Question

Using the impulse momentum theorem,

The question:

Suppose a player hits a ball of mass 0.145 kg with a racket, and that the velocity of the ball before hitting the racket is -38 m/s. Assuming the positive direction towards the pitcher, the initial momentum of the baseball is: pi=(0.145kg) (-38m/s) =--5.5kg.m/s .) What is the momentum of the ball after the collision? Apply the theory of impulse and momentum to find the final momentum

Answer 1

The momentum of the ball after the collision is

$$p_f=-p_i=5.5\text{ kg m/s}.$$
