Answer:
The change in gravitational potential energy of the climber-Earth system,[tex]\Delta E=4.49\times 10^5\ J[/tex]
Explanation:
Given that,
Mass of the hiker, m = 85 kg
Time, t = 2 h
Vertical elevation of the climber, h = 540 m
We need to find the change in gravitational potential energy of the climber-Earth system. We know that due to change in position of an object, gravitational potential energy occurs. It is given by :
[tex]\Delta E=mgh\\\\\Delta E=85\times 9.8\times 540\\\\\Delta E=4.49\times 10^5\ J[/tex]
So, the change in gravitational potential energy of the climber-Earth system is [tex]4.49\times 10^5\ J[/tex]. Hence, this is the required solution.
