Help on a physics question?

Two hockey pucks of equal mass undergo a collision on a hockey rink. One puck is initially at rest, while the other is moving with a speed of 5.4 m/s. After the collision, the velocities of the pucks make angles of 33° and 46° relative to the original velocity of the moving puck. Determine the speed of each puck... show more Two hockey pucks of equal mass undergo a collision on a hockey rink. One puck is initially at rest, while the other is moving with a speed of 5.4 m/s.
