Question

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 m, = 80.0 kg moves in the negative y-direction at
4.00 m/s and skater B with mass m, = 95.0 kg moves in the negative x-direction
at 3.50 m/s. Find the x- and y-components of the 90.0 kg skater C's velocity
(in m/s) after the push.
