High-speed stroboscopic photographs show that the head of a golf club of mass 231g is traveling at 59.0m/s just before it strikes a 47.1g golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 44.3m/s. Calculate the speed of the golf ball just after impact.

Answer 1

momentum lost by club=momentum gained by ball

231(59-44.3)=47.1(Speed)
calculate speed.
