1. The problem statement, all variables and given/known data Object 1 pushes on object 2 as the objects move together, like a bulldozer pushing a stone. Assume object 1 does 15.0 J of work on object 2. Does object 2 do work on object 1? 3. The attempt at a solution My answer is yes, the object 2 does work on object 1 as a resistive force. However, how do I know the exactly work that done by the object 2? 2 objects are moving together without mention under a constant velocity or acceleration. I've no clue on this.
