High-speed stroboscopic photographs show that the head of a golf club of mass 200 g is traveling at 55.0 m/s just before it strikes a 46.0-g golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 40.0 m/s. Find the speed of the golf ball just after impact.
I assume you mean the velocity is (3i-4j)
so momentum in the i (x) direction is 9, and in the j(y) direction is -12
Momentum before=momentum after
MV+0=MV' + mv'
so v' (velocity ball)= massclub(55-40)/massball

omg i absolutely love you bobpursley! thankss for the help as well. =]
