A 97.5-kg man pushes a crate 4.5 m up along a ramp that makes an angle of 17.5° with the horizontal. He exerts a force of 495 N on the crate parallel to the ramp and moves it at a constant speed. Calculate the work, in joules, that the man performs to cause the crate and himself to move up the ramp.
