Betty Bodycheck (mB = 51.1 kg, vB = 22.0 km/h in the positive x-direction) and Sally Slasher (mS = 40.5 kg, vS = 28.0 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 76.0° 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. What are Betty and Sally's final kinetic energies? http://www.webassign.net/bauerphys1/7-p-055.gif Kinetic Energy: K=(1/2)mv^2 ........ Momentum: p=mv When I attempted this problem I first converted both velocity from km/h to m/s. Next I proceeded to calculate Betty's and Sally's KE: [Betty] (1/2)x51.1x(6.11278)^2= 954 J......[Sally] (1/2)x40.5x(7.7779)^2=1225 J. Both answers were wrong, a few step(s) or missing equations are missing I believe but I do not know what. Can anyone please help? Thank You.
