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 = 75.0 kg
moves in the negative y-direction at 3.00 m/s and skater B with mass
mB = 70.0 kg
moves in the negative x-direction at 4.00 m/s. Find the x- and y-components of the 90.0 kg skater C's velocity (in m/s) after the push.
