Right option is (a) 0
The best explanation: By work-energy theorem, the total work done on a body is equal to the change in the total energy. K.E. = \(\Big(\frac{1}{2}\Big)\)mv^2 and P.E. = mgh. One can find out the total change in the kinetic and potential energies at the initial and the final points, i.e. at the starting and after covering a distance of 8.75 m. The total change in the total energy is 0. Hence the work done is 0.
