A cue ball travelling at 5.0 m/smakes a glancing, elastic collision with a target ball of equalmass that is initially at rest. The cue ball is deflected so thatit makes an angle of 30° with its orginal direction of travel.
(a) Find the angle between the velocity vectors of thetwo balls after the collision.
°(b) Find the speed of each ball after the collision.
cue ball m/s
target ball m/s
