In a game of pool, a cue ball with an initial velocity of 2.10 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 1.82 m/s at an angle of 30.0 degrees above the +x direction. (a) Find the cue ball's final velocity. magnitude=   direction= below the positive x-axis (b) Is kinetic energy conserved? Yes or No
