4. A crate of mass 15 kg is pulled up a rough incline with an initial speed of 1.5 m/s. The pulling force is 100N parallel to the incline, which makes an angle of 20° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 5.00m. (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 150N force? (d) What is the speed of the crate after being pulled 5.00m?
