Exercise 56

A major league catcher catches a fastball moving at 950 mi/h and his hand and glove recoil 10.0 cm in bringing the ball to rest. If it took 0.00470 s to bring the ball (with a mass of 250 g) to rest in the glove, (a) what are the magnitude and direction of the change in momentum of the ball (b) Find the average force the ball exerts on the hand and glove.
