Work and Energy Question?? PLZ Help!
Hi, I am having a stupid question with a classic work and engergy problem.
Suppose you have A 50-kg crate is pulled 40m along a horizontal floor by a constant force exerted by a person, F done of by the pulling force is 100N, which at 37 degrees. F done by the friction is 50N.
I calculated the work done by the pulling force, which is 3200J.
I also calculated the work done by the frictional force, which is -2000J.
My question is what happened to the net work, 1200J.
Does the energy stores inside the crate, what?
PLZ HELP!
