When a 0.045-kg golf ball takes off after being hit, its speed is 41 m/s. (a) How much work is done on the
ball by the club? (b) Assume that the force of the golf club acts parallel to the motion of the ball and that
the club is in contact with the ball for a distance of 0.010 m. Ignore the weight of the ball and determine the
average force applied to the ball by the club.
