This is the scenario. --- A good guy and a bad guy crash their rocketships. The place has virtually no friction and no air. They fall into a ditch, and they can't climb out (because there is no friction). They CAN get out, but only one at a time. If the good guy gets out first, then he'll probably help the bad guy get out. If the bad guy gets out first, then he might not help the good guy. So how can they get out? --- I think Newton's laws would be useful in solving this...but otherwise i am VERY clueless. i need to turn this in tomorrow, PLEASE HELP!
