Question

10. A Sherpa of mass 80 kg is instructed to carry a package
of mass 20 kg from the base camp to the summit of a
mountain 1200 m high. (i) How much work the Sherpa
has to do against gravity? (ii) Also, find the change in
potential energy of the package if the potential energy
at the base of the mountain is taken as zero.
(Take g = 10 m s-2) (Ans. 1.2 * 106 J, 2.4 x 1053)​
