A hockey puck moving at 0.473 m/s collides elastically with another puck that was at rest. The pucks have equal mass. The first puck is deflected 36.8° to the right and moves off at 0.284 m/s.
Find the speed of the second puck after the collision.
Calculate the direction (angle) of the second puck after the collision. Consider positive to be to the right and negative to be to the left.
