When a golf club strikes a golf ball, the club is in contact with the ball for about .0016 s. The 45-g ball acquires a speed of 71 m/s.
a) What is the magnitude of the impulse applied to the ball?
b) Estimate the magnitude of the average force exerted by the club on the ball in kilo-Newtons.
Force*time=change in momentum=mass*changeVelocity
