In a game of pool, a cue ball with an initial velocity of 1.25 m/s directed to the right (along the +x-axis) collides with the five ball, which has equal mass and is initially at rest. The five ball then moves at 1.08 m/s at an angle of 30.0° above the +xdirection. (a) Find the cue ball's final velocity. magnitude   direction below the positive x-axis (b) Is kinetic energy conserved? Yes No
