Starting from rest, two skaters 'push off' against each other on smooth
level ice, where friction is negligible.
As the drawing shows, one
is a woman (m1 = 54 kg), and one is a man (m2 = 88 kg).
Part b of the drawing shows that the woman moves away with a velocity
of vf1 = +5.5 m/s.
Find the "recoil" velocity vf2 of the man.
