Energy Lost Due To Friction

[Laplace]

My method gives the average acceleration loss.

But your method is not intuitive, so how can it be the conceptually simpler approach?

Why do you think it is not intuitive? Does it not make sense to realize that the longer the trolley takes to descend he incline, the more friction resistance is present? The simple concept of friction slowing the descent is in play for this problem.

It is not a question of "why", it is a question of "whether" your method is intuitive. It is not.

To be complete, the next question after whether is why. I believe both of our answers are equally intuitive, but mine is easier to determine.
