Question

A man climbs up a slope and another walks same distance on level road. Who does more work and why?

Answer 1

the man that climbs does more work because he had faced the friction and acceleration that has been produced by his feet and the steep slope

Answer 2

Answer:same

Explanation:

Work done is a path independent quantity. We assume in both cases force application is same (ideal conditions )thus work done becomes proportional to displacement. Since it has been said that the displacement is same therefore IN BOTH CASES WORK DONE AND ENERGY USED IS SAME.
