When a cue ball strikes the 8-ball, we can assume that the collision is elastic. An 8-ball has a mass of 0.160 kg, and we have made a special cue ball, with a lead core, to have a mass that is 3 times as much as the 8-ball's mass, or 0.480 kg. Let's say this heavy cue ball, initally moving at 1.5 m/s, strikes the 8-ball, and the 8-ball's subsequent velocity is in the same direction as the initial velocity of the cue ball. In other words, the two balls make a one dimensional elastic collision.

7. We found that if a cue ball, rolling without slipping at speed v0, strikes an identical, stationary billiard ball head-on, eventually both balls will roll without slipping. The balls are uniform solid spheres, each of mass m, radius r, and moment of inertia I =2/5 m r^2 about its center. The final speed of the target ball is 5/7 *v0 ; that of the cue ball is 2/7 v0. Calculate the total fraction of the initial kenetic energy of...
