A cue ball m1 = 0.395 kg is shot at another billiards ball m2 = 0.51 kg which is at rest. The cue ball has an initial velocity of v = 6.5 m/s. Assume that the collision is elastic. 

(a) Write an expression for the billiard ball's velocity v2f after the collision. 

(b) What is the velocity in m/s? 

(c) Write an expression for the cue balls velocity after the collision v1f. 

(d) What is the cue balls final velocity in m/s?
