After the collision, the cue ball moves at 4.35 m/s along a n a game of pool, the cue ball strikes a vith the cue bail's original direction of motion ( notion of the cue ball, (the x axis), and the second ball has a speed of 3,098 m/s. Find the angle between the direction of motion of Submil Answer Tries o/20 of the cue ball. Submit Answer Tries 0/20 kinetic energy (of the centers of mass, don't consider the rotation) conserved? You are correct. Computer's answer now shown above rourreceipt no.is 164-4783 Send Feedback Post DiscussionExplanation / Answer
a) vball sin theta = vcue * sin 20
sin theta = 4.55 * sin 20 / 3.098
theta = 30.15 deg
b) vcue, ini = vcue, final cos 20 + vball * cos 30.15
= 4.55 *cos 20 + 3.098 * cos 30.15
= 6.95 m/s
