Starting from rest, two skaters "push off" against each other on smooth level ice, where friction is negligible. One is a woman and one is a man. The woman moves away with a velocity of +2.7 m/s relative to the ice. The mass of the woman is 61 kg, and the mass of the man is 81 kg. Assuming that the speed of light is 3.8 m/s, so that the relativistic momentum must be used, find the recoil velocity of the man relative to the ice.
