When a golfer tees off, the head of her golf club which has a mass of 280 g is traveling 58 m/s just before it strikes a 46-g golf ball at rest on a tee. Immediately after the collision, the club head continues to travel in the same direction but at a reduced speed of 51 m/s. Neglect the mass of the club handle and determine the speed of the golf ball just after impact.
