Problem

A person pulls a bucket of water from a well of depth hh. If the mass of the uniform rope is mm and that of the bucket full of water is MM, the work done by the person is: (1) (M+m2)gh\left(M+\frac{m}{2}\right)gh (2) 12(M+m)gh\frac12(M+m)gh (3) (M+m)gh(M+m)gh (4) (M2+m)gh\left(\frac{M}{2}+m\right)gh
