Problem

A tennis ball with momentum

2.3\text{ kg m/s}

is struck by a tennis racket. The racket causes the direction of motion of the ball to reverse. The racket exerts an average force of

1500\text{ N}

during the impact with the ball. The racket and ball are in contact with each other for a time of

0.0024\text{ s}

. What is the magnitude of the momentum of the ball as it leaves the tennis racket? A)

1.3\text{ kg m/s}

3.6\text{ kg m/s}

5.9\text{ kg m/s}

8.6\text{ kg m/s}
