Question

Three mountain climbers set out to climb a mountain from the same altitude and all arrive at the same location at the top. Mountain climber A took a long gradual slope to the top, B went a steeper but shorter path, and C tackled the sheer straight side to the top. Assume all three climbers have the same mass. Which climber gained the greatest potential energy?A. AB. BC. CD. all did the same amount of work

Answer 1

Answer:All did same amount of work

Explanation:

All three mountain climbers took different routes to reach the peak. There is a constant gravity force acting on the object i.e. gravity force. Gravity force is conservative i.e. work done by a conservative force is independent of the path followed.

Therefore work done by all the mountain climbers is the same i.e. all did the same amount of work.
