Three ice skaters meet at the center of a rink and each stands at rest facing thecenter, within arm’s reach of the other two. On a signal, each skater pushes themselves away fromthe other two across the frictionless ice. After the push, Skater A with mass 80 kg moves in thenegative y-direction at 3.5 m/s and skater B with mass 75 kg moves in the negative x-direction at4 m/s. Find the x- and y-components of the 90 kg Skater C’s velocity after the push. Assume abirds-eye view of the situation for your coordinates.

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 themselves away from
the other two across the frictionless ice. After the push, Skater A with mass 80 kg moves in the
negative y-direction at 3.5 m/s and skater B with mass 75 kg moves in the negative x-direction at
4 m/s. Find the x- and y-components of the 90 kg Skater C’s velocity after the push. Assume a
birds-eye view of the situation for your coordinates.
