A cue ball of mass m1 = 0.325 kg is shot at another billiard ball, with mass m2 = 0.505 kg, which is at rest. The cue ball has an initial speed of v = 7.5 m/s in the positive direction. Assume that the collision is elastic and exactly head-on.
(a) What is the horizontal component of the billiard ball's velocity, v2f, after the collision, in meters per second?
(b) What is the horizontal component of the cue ball's final velocity, v1f, in meters per second?
