Homework Help: physics

Posted by mitch on Sunday, October 1, 2006 at 11:18pm.

if a child pulls an old wagon up a steep incline on a sidewalk, what does a child's work do?

i say, it would increase, due to the fact that it is a steep hill and it takes more work to pull the wagon up???


The child's work is done aganst gravity, and results in an increase in the potential energy of the wagon. That increase equals the work done, neglecting friction.
