Calculate the work done (in J) by a 75.0 kg man who pushes a crate 4.30 m up along a ramp that makes an angle of 20.0° with the horizontal. (See the figure below.) He exerts a force of 540 N on the crate parallel to the ramp and moves at a constant speed. Be certain to include the work he does on the crate and on his body to get up the ramp.
