Chapter 9, Problem 80MSPP

Consider a golf club hitting a golf ball. To a good approximation, we can model this as a collision between the rapidly moving head of the golf club and the stationary golf ball, ignoring the shaft of the club and the golfer.

A golf ball has a mass of 46 g. Suppose a 200 g club head is moving at a speed of 40 m/s just before striking the golf ball. After the collision, the golf ball’s speed is 60 m/s.

79. What is the momentum of the club + ball system right before the collision?

A. 1.8 kg · m/s

B. 8.0 kg · m/s

C. 3220 kg · m/s

D. 8000 kg · m/s
