**drwls**, Thursday, December 9, 2010 at 2:05amAre you supposed to assume the process is frictionless? I can't imagine a frictionless box on a ramp.

Conservation of energy would be a good way to attack the problem.

Subtract the potential energy increase from the work done by the person pushing.

If there is no friction, the difference will be the kinetic energy increase.
