In a pool game the cue ball A must strike the eight ball in the position shown in order to send it to the pocket P with a velocity v₂′. The cue ball has a velocity v₁ before impact and a velocity v₁′ after impact. The coefficient of restitution is 0.9. Both balls have the same mass and diameter. Calculate the rebound angle θ and the fraction n of the kinetic energy which is lost during the impact.
