A rock climber (m = 70 kg with gear in included) starts at the base of a cliff and climbs to the top (h = 36 m). He then walks along the plateau at the top for a distance L = 47 m. Find the work done by gravity and the change in gravitational potential energy of the rock climber. Part 1 - Recognize the Principles Which of the following principles or statements will or might be helpful in solving this problem? (Select all that apply.) The gravitational potential energy of an object near the Earth's surface is mgh. The work done by a force acting on an object is given by W = Fd cos 6. For a conservative force, the change in the potential energy equals the negative of the work done by the force. Gravity is a conservative force.
