2) (introduction) A person pulls a bucket of water up from a well with a rope. Assume the initial and final speeds of the bucket are zero, (v = vf = 0), and that the person lifted the bucket a vertical distance h. By looking at energy changes in the bucket-Earth physical system, we can make sense of the force the person must exert to pull the bucket up and the amount of work the person does. a) Think about whether this is an open or closed system. Which energies undergo a change during the process? Construct a particular Energy-Interaction diagram for this process and include the algebraic expression of energy conservation (in terms of AE's and if open, any Heat or Work).
