High-speed stroboscopic photographs show that the head of a golf club of mass 230g is traveling at 56.1m/s just before it strikes a 44.6g golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 41.4m/s. Calculate the speed of the golf ball just after impact.

momentum is conserved.
massclub*velocityinitial=massball*speedball+mass club*speedfinal club

massclub(vi-vf)=massball*speedball
speedball=massclub/massball * (56.1-44.6)
