momentum physics question

Question

Two men, of mass 100 kg each, stand on a cart of mass 300 kg. The cart can roll with negligible friction along a north-south track, and everything is initially at rest. One man runs towards the north and jumps off the cart at a speed of 5.0 m/s, relative to the cart. After he has jumped, the second man runs towards the south and jumps off the cart, again with a speed of 5.0 m/s relative to the cart. Calculate the speed and direction of the cart after both men have jumped off.

Hi Alex J.

You've submitted 5 questions covering the same material (more or less), at the same time. This suggests that you're trying to get tutors to answer your entire problem set. That's not the purpose of Wyzant, it's to show you how to do a problem, then you can use the knowledge yourself to do the rest.
