Homework Statement
Two men, of mass 100kg each, stand on a cart of mass 300kg.The cart can roll with negligible friction along a north-south track, and everything is initially at rest. One man runs toward the north and jumps of the cart at 5 m/s, relative to the cart. After he jumps, the second man runs to the south end and jumps off at 5 m/s relative to the cart. Calculate the speed and direction of the cart after both men have jumped off.
Homework Equations
Ek=1/2mv^2
The Attempt at a Solution
I don't know how to begin since it is at rest and there for Ek is 0 meaning every other step of this should be 0.
