Problem

Two ice skaters, initially at rest on frictionless ice, push off each other. Skater A has a mass of 60 kg60\,\text{kg} and glides westward at 2.0 m ⁣⋅ ⁣s−12.0\,\text{m}\!\cdot\!\text{s}^{-1} immediately after they separate. Skater B has a mass of 50 kg50\,\text{kg}. What is skater B’s velocity just after the push? a) 2.0 m ⁣⋅ ⁣s−12.0\,\text{m}\!\cdot\!\text{s}^{-1} east b) 2.4 m ⁣⋅ ⁣s−12.4\,\text{m}\!\cdot\!\text{s}^{-1} east c) 2.4 m ⁣⋅ ⁣s−12.4\,\text{m}\!\cdot\!\text{s}^{-1} west d) 1.6 m ⁣⋅ ⁣s−11.6\,\text{m}\!\cdot\!\text{s}^{-1} east
