1. The problem statement, all variables and given/known data A man picks up a 10kg box, and holds it at a height of 1m above the horizontal ground as he walks to a ramp, and then carries the box up the ramp to a height of 4m, and then down the ramp as shown, finally placing it on the ground at F. Describe the work done at each stage of the motion. What is the net work done on the box? 2. Relevant equations W=Fdcos[tex]\theta[/tex] 3. The attempt at a solution Not really sure with this one. I said A-->B = no work done. B-->C = work done (don't think that's a good description though!). C-->D = no work done. D-->E = work done (would this be negative (or positive) work? E-->F = no work done. So, the net work done on the box would = 0.
