Question

One of the world's most famous climbing rocks is the 884 m El Capitan in Yosemite National Park. A common climbing route, involves an overnight stay on a ledge. For a typical 75kg male climber, the change in gravitational potential energy from the bottom to the top of El Capitan is about 6.5 x10^5 J. That sounds like a lot, but in fact, it's less than the energy you get from eating a typical candy bar! the work that results in the net change in gravitational potential energy represents just a small part of the total energy expended on such a climb..

Do the same calculations for your favorite climb/hike (or a different famous climb).
