Question

A billiard ball, labeled 1, moving horizontally strikes another billiard ball, labled 2, at rest. Before the impact ball 1 was moving at a speed of 5 m/s and after the impact it is moving at a speed of 2 m/s at an angle of 50 degrees from the original direction. The two balls have equal mass.

Write conservation of momentum equations for the x and y directions separately and solve for the speed of ball 2 after the impact.
