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

Answer:
7.5 units
Explanation:
Since, the length of the hypotenuse =15 unit
We know that,
Median =
