Calculate the work done (in J) by an 80.0 kg man who pushes a crate 4.05 m up along a ramp that makes an angle of 20.0° with the horizontal (see below). He exerts a force of 460 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.

Step 1
In this case, the force applied is the force of gravity (mg) and the distance moved is the length of the ramp (d). Show more…

What force is needed to move the crate up the ramp with constant velocity if the ramp is at an angle of 30°?
Adi S.
A man pulls a 100 N crate up a frictionless 30° slope 5 m high, as shown. Assuming that the crate moves at a constant speed, the work done by the man is
