A cue ball of mass m1 = 0.395 kg is shot at another billiard ball, with mass m2 = 0.54 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) Write an expression for the horizontal component of the billiard balls velocity, v2f after the collision, in terms of the other variables of the problem. b) What is this velocity, in meter per second? c) Write an expression for the horizontal component pf the cueball’s velocity, v1f after the collision. d) What is the horizontal component of the cue ball’s velocity, in meter per second?
