High-speed stroboscopic photographs show that the head of a golf club of mass 210 g is traveling at 52.7 m/s just before it strikes a 44.0 g golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 41.4 m/s. Find the speed of the golf ball just after impact. My attempt: E=mv^2 E=(.210)(52.7)^2 E=583.2309J Energy in the club after striking the ball E=.210(41.4)^2 E=359.9316 The energy that is transferred to the golf ball = 583.2309-358.9316=223.2993J Therefore the velocity must be 223.2993=.01v^2 v^2=22329.93 v=149.432 But this is wrong. What am i doing wrong?
