Three ice skaters meet at the center of a rink and each stands at rest facing the center, within arm's reach of the other two. on a signal, each skater pushes himself away from the other two across the frictionless ice. after the push, skater a with mass ma = 90.0 kg moves in the negative y-direction at 4.00 m/s and skater b with mass mb = 85.0 kg moves in the negative x-direction at 3.50 m/s. find the x- and y-components of the 95.0 kg skater c's velocity (in m/s) after the push. hint
