Question

As a crate slides down an inclined rough surface, its total mechanical energy A) increases, B) might decrease or increase depending on size of slope angle, C) decreases, D) might increase or decrease depending on the friction coefficient is, or E) remains constant.

Answer 1

I think the correct answer from the choices listed above is option D. As a crate slides down an inclined rough surface, its total mechanical energy might increase or decrease depending on the friction coefficient. Hope this answers the question.
