Physics

A puck with a mass m1 = 28.0 g moving at 1.00 m/s approaches astationary puck with a mass m2 = 102 g on an air table and theyundergo a two-dimensional elastic collision. As a result of theirinteraction, the incident puck moves away with a speed v1 = 0.785m/s and the other puck moves away with a speed v2 in a differentdirection. What is the angle between the velocities v1 and v2 ?

Explain please!!!
