A pool ball moves with a velocity of 5m/s, it hits another ball
(with the same mass) which is in repose. After collision, the first
ball moves with a velocity of 4.33m/s and an angle of 30° (in
respect to the original line of movement). Assuming it's an elastic
collision, find the velocity and angle of the second ball.
Answer: Vf=2.5m/s at 300°

In a game of pool, the cue ball strikes another ball of the same mass and initially at rest. After the collision, the cue ball moves at 2.10 m/s along a line making an angle of 12.0° with its original direction of motion, and the second ball has a speed of 1.50 m/s. Find (a) the angle between the direction of motion of the second ball and the original direction of motion of the cue ball and (b) the original...
