Question

A crate is placed at the upper end of the 2.0 m long ramp that is inclined at 20° to the horizontal and allowed to slide down the ramp starting from rest. The crate has a mass of 150 KG and the coefficient of kinetic friction between the crate and then incline is 0.25. Draw a diagram showing all the forces acting on the crate. How much work is done by the gravity on the crate during the slide? How much work is done by friction during the slide? Use the work energy theorem to calculate the speed attained at the bottom of the ramp.Also,Which force does no work during the slide, and why?
