An 7.7 kg crate is pulled 5.0 m up a 30∘ incline by a rope angled 16 degrees above the incline. The tension in the rope is 100 N and the crate's coefficient of kinetic friction on the incline is 0.25.

How much work is done by tension, by gravity, and by the normal force?

What is the increase in thermal energy of the crate and incline?
