5. Calculate the work done by an 70.2 kg man who pushes a crate 4.25 m up along a ramp that makes an angle of 20.1 with the horizontal. (See Figure 7.32.) He exerts a force of 599 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. Figure 7.32 A man pushes a crate up a ramp. Work done on the Crate: Work done on his body: Total work done:
