Question

a mountaineer climbs to the top of a hill 200m above the ground level what is his potential energy at a point

Answer 1

The mountaineer's potential energy at the top of the hill is equal to the work done to get there, which is equal to the mass of the mountaineer multiplied by the gravitational acceleration (9.8 m/s2) multiplied by the height of the hill (200 m). Therefore, the mountaineer's potential energy at the top of the hill is 19,600 Joules.
