skates, at rest and facing each other, with a compressed spring between them. The spring is kept from pushing them apart, because they are holding each other. When they release their arms, Al moves off in one direction at a speed of 0.910 m/s, while Jo moves off in the opposite direction at a speed of 0.829 m/s. Assuming that friction is negligible, find Al's mass
