1. The problem statement, all variables and given/known data In trying to lift a sandbag B attached to the rope as in the attached figure, a worker at the top of the scaffolding dumps his tools and lunch kit into the box A so that it is now 80kg. if the sandbag is 65kg, find its speed as it hits the scaffolding. Assume that the sandbag starts from rest. 2. Relevant equations W=Fd Win = change in kinetic + change in potential + Wout 3. The attempt at a solution I started by drawing 2 free body diagrams. Can someone guide me? Not too sure where to start.
