    [SOLVED] Conservation of Momentum problem-don't understand the solution

    1. The problem statement, all variables and given/known data

    The drawing shows a collision between two pucks on an air-hockey table. Puck A has a mass of 0.025kg and is moving along the x axis with a velocity of 5.5m/s. It makes a collision with puck B, which has a mass of 0.050kg and is initially at rest. The collision is not head-on. After the collision, the two pucks fly apart with the angles shown in the drawing. Find the final speed of (a) puck A and (b) puck B.

    2. Relevant equations
