Problem
A tennis ball with momentum 2.3 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 N during the impact with the ball. The racket and ball are in contact with each other for a time of 0.0024 s.
What is the magnitude of the momentum of the ball as it leaves the tennis racket?
(A) 1.3 kg m/s
(B) 3.6 kg m/s
(C) 5.9 kg m/s
(D) 8.6 kg m/s
