Kyle asked:


High-speed stroboscopic photographs show that the head of a 180 g golf club is traveling at 44 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 36 m/s. Find the speed of the golf ball just after impact.

    Use conservation of momentum

    before p = m*v = 0.180*44 = 7.92kg-m/s

    after 0.180*36 + 0.046*V

    So V = (7.92 - 0.180*36)/0.046 = 31.3m/s
