High-speed stroboscopic photographs show that the head of a golf club of mass 220 grams is traveling at 50 m/s just before it strikes a 46-gram golf ball at rest on a tee. After the collision, the clubhead travels (in the same direction) at 36 m/s. Find the speed of the golf ball just after impact. Is the collision between the clubhead and the golf ball elastic or inelastic. Why
