A5

A5.0 kg hockey puck is sliding horizontally on a frictionless surface at 10.0 m/s and collides perfectly elastically with two hockey pucks that weigh 2.5 kg each.

Puck #1 moves away from the collision at a speed of 1.5 m/s and an angle of 30° from the horizontal.

At what speed and angle does puck #2 move away from the collision?
