5. A box of mass 16 kg is pulled up a rough incline with a speed of 1.5 m/s. The force applied by pulling is 150N parallel to the incline, which has an angle of 30° with the horizontal. if coefficient of kinetic friction is 0.4, 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?
