A cue ball (0.17 kg) is moving at a velocity of 11.3 m/s when it strikes two billiard balls (0.16kg), at rest, "dead center" and comes to rest. If one billiard ball moves at a velocity of 4.1 m/s at an angle of 39 radians measured clockwise relative to the incoming direction of the cue ball, and another ball moves at an angle measured counter-clockwise relative to the incoming direction of the cue ball, how fast is the second ball moving in m/s?
