Bob and Linda are sweethearts that enjoy skating arm in arm. Bob has a
mass of 85 kg and Linda has a mass of 60 kg. Initially they are skating together with
a speed of 3.0 m/s. Then Bob whispers a dirty joke into Linda's ear, causing her to
push him in the oppposite direction of their motion. If Bob's final speed is 1.0 m/s,
what is Linda's final speed?
