A man pulls a crate of mass 8 kg which is on frictionless bearings up a ramp that is h = 5 m high and angled at 37°. The crate goes from rest at the bottom to rest at the top of the incline. (Hint: Remember the direction of force and displacement.) (a) How much work is done by the man?
(b) How much work is done by gravity?
(c) How much work is done by the normal force?
