(a)[2]
Define the term work done.
(b)[2]
The flag has a mass of $0.35\,\text{kg}$ and is lifted through $6.0\,\text{m}$. With $g=10\,\text{N kg}^{-1}$, Calculate the increase in gravitational potential energy of the flag.
(c)[2]
Suggest and explain why the work done on the rope is greater than the value obtained in (b).
