Need help on simple problem

  1. Oct 26, 2005 #1
    Heres the problem:

    An 8.00 kg mass moving east at 14.8 m/s on a frictionless horizontal surface collides with a 10.0 kg object that is initially at rest. After the collision, the 8.00 kg object moves south at 3.70 m/s.

    a. what is the velocity of the 10.0 kb object after the collision?
    magnitude:____ m/s
    direction: ____ (degrees)

    b. what percentage of the initial kinetic energy is lost in the collision?

    thanks guys!
