1. The problem statement, all variables and given/known data If 100 joules of energy is transferred from a mover to a box, does the mover do 100 joules of work on the box or does the box do 100 joules of work on the mover? Does the box lose energy? 2. Relevant equations W=F*d 3. The attempt at a solution I don't think the box loses energy because 100 joules are transferred to it from the mover. I don't think the box does work on the mover because no movement is indicated. Same goes for the mover, no work is done because no distance is indicated?
