Why is it easier to climb a mountain via zig-zag trail rather than to climb straight up.
Answer to Problem 25Q
Solution:
It is easier to climb a zig-zag mountain since the power supplied is less than the power used to climb the mountain directly.
Explanation of Solution
Given:
Climb a mountain in a zig-zag vs climbs a mountain directly.
The same amount of work is done if you climb directly or follow the zig-zag path. The amount that varies is the power supplied to go up. When the time to rise increases (zig-zag)then the power supplied by the body is less than if you rise directly for a shorter time. If the power supplied is less for a longer time, the muscles of the hikers become less fatigued. Otherwise, if you go up directly, the elapsed time is less but it requires more power to achieve it, which causes greater fatigue in the muscles.
