Assume my equipment and I have a combined mass of 115 kg. And I go for a hike starting at Yosemite Valley (elevation = 1219 meters) and I walk up to the top of Half Dome (elevation = 2694 meters). What is my change in gravitational potential energy? If this hike-climb takes 7 hours, what is my average power output?

Calculate your potential energy at the bottom as zero, and at the top as 2694-1219=1475 meters up. Gravity's acceleration is 9.8 m/(s^2).
Then, your physics textbook will have the necessary forumlae for (1) calculating potential energy, and (2) calculating work and power.

Did you know that Gravity is a push and not a pull!
