1. A crate of mass 10.0 kg is pulled up a rough 20 degrees incline. The pulling force is 100 N parallel to the incline. The coefficient of kinetic friction is 0.4 and the crate is pulled 5.0 m. Show complete solution please. (a) How much work is done by gravity? (b) How much energy is lost due to friction? ( c) How much work is done by the 100N-force? (d) How much work is done the normal force? (e) What is the total or net work done on the crate? (f) If the package is pulled from rest, what is the speed of the crate after it has been pulled 5.0m? Use Work-energy equation (g) If the package is pulled with an initial speed of 1.5 m/s, what is the speed of the crate after it has been pulled 5.0 m? Use Work-energy equation
