Problem: High-speed stroboscopic photographs show that the head of a 270-g golf club is traveling at 53 m/s just before it strikes a 46-g golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 38 m/s.
Part A: Find the speed of the golf ball just after impact.
I need help to determine the speed of the golf ball just after impact.
