Question
A golf ball with mass 4.50 10-2 kg is struck with a club as shown in the figure above. The force on the ball varies from zero when contact is made up to some maximum value (when the ball is maximally deformed) and then back to zero when the ball leaves the club, as in the graph of force vs. time in the figure below. Assume that the ball leaves the club face with a velocity of +50 m/s.
(a) Find the magnitude of the impulse due to the collision.
kg · m/s
(b) Estimate the duration of the collision and the average force acting on the ball. (Assume the distance the ball travels on the face of the club is 2 cm, roughly the same as the radius of the ball.)

If the ball is in contact with the bat for a time of 1.27 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the bat, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction.
