Statement

2.7.32∗. On a smooth horizontal plane, two identical thin rotating rings move towards each other. Their velocities v1 and v2 are directed along a staright line connecting the centers of rings. Angular velocities of the rings w1 and w2. Determine the angular velocities of the rings after impact, if their slippage relative to each other disappears at the last moment of impact?
