The white ball in the figure has a speed of 1.64 m/s and the yellow ball is at rest prior to an elastic glancing collision. After the collision the white ball has a speed of 1.2 m/s. To the nearest tenth of a degree, measured counterclockwise from east, WHAT ANGLE does it scatter at if the yellow ball is scattered at 280 degrees?

In a pool game, the cue ball, which has an initial speed of 2.5 m/s, makes an elastic collision with the 8-ball, which is initially at rest. After the collision, the 8-ball moves at an angle theta = 14.3 degrees with respect to the original direction of the cue ball. Assume the pool table is frictionless and the masses of the cue ball and the 8-ball are equal. The cue ball travels at an angle of 90 degrees after the...
