Matthew pushes a box of toys along a 5 m long ramp that is inclined 3 m high as shown in the figure below. The box has a total mass of 20 kg and the coefficient friction between the box and the ramp is 0.33. (a) How much force is needed by Matthew to move the box uniformly along the inclined ramp? (b) How much work is done by the force the box has travelled the 5.0 m length incline? (c) How much work is done by friction? (d) How much work is done by gravity? (e) How much work is done by the normal force? (f) What is the total work done by all the forces on the box?
