A 15kg crate is moved along a horizontal floor by pulling on it with a rope that makes a 30 degree angle with the horizontal. The tension in the rope is 200N and the crate slides a distance of 10m. If the coefficient of kinetic friction between the crate and the floor is 0.4
A) How much work is done by the normal force
B) How much work is done by frictional force
C) How much work is done on the crate by the rope
D) What is the net work?
