Let's assume you also have a ramp available that makes an angle of 30° with the horizontal. The ramp is 2x = 1.6 m long. The weight of the box (350 N) is due to the Earth pulling on the box. This F = 350 N is a force directed straight down. If you push it up a ramp, you are doing work against only the component of this weight along the ramp, which is Fx = 175 N. How much work does it require to push the box up the ramp, assuming no friction?
