When a 0.045 kilogram golf ball takes off after being hit, its speed is 35 m/s.
(a) Determine how much work is done on the ball by the club?
(b) Suppose 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 0.020 meter. Neglect the weight of the ball and find the average force applied to the ball by the club.
