A billiard ball, labeled X, moving horizontally, strikes another billiard ball, labeled Y, at rest. Before impact, ball X was moving at a speed of 3.1 m/s, and after impact it is moving at 0.50 m/s at 50.° from the original direction. If the two balls have equal masses of 0.274 kg, what is the velocity of the ball Y after the impact? Give your answer in meters/second only; ignore direction.
