Betty Bodycheck (mB = 50.2 kg, vB = 22.0 km/h in the positive x-direction) and Sally Slasher (mS = 45.2 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 their final kinetic energy?

  • physics - ,

    Total or separately?
    Write the two equations of conservation of momentum in x and y directions. Sinc e you know the final directions, you can solve for the two unkonwn speeds.

    With the final speeds, you can compute the final kinetic energy of each person

    I did that but i am not getting the right answer

  • physics - ,

    ok does anyone know how to do this i need step by step help on this
