Betty Bodycheck (me = 55 kg. V = 22 km/h in the positive x-direction) and Sally Slasher (ms = 45.0 kg, Vs = 28 km/h in the positive y-direction) are both racing to get to a hockey puck. Immediately after the collision. Betty is heading in a direction that is 76 counterclockwise from her original direction, and Sally is heading back and to her right in a direction that is 12.0 from the x-axis.
