Find the cue balls final velocity

Reference no: EM13495330

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 +x direction.

(a) Find the cue ball's final velocity

Magnitude=_________

Direction=___________ below positive x axis

(b) Is kinetic energy conserved?

Yes or No ?
