In Figure 12-42 a 57 kg rock climber is in a lie-back climb along a fissure, with hands pulling on one side of the fissure and feet pressed against the opposite side. The fissure has width w = 0.15 m, and the center of mass of the climber is a horizontal distance d = 0.50 m from the fissure. The...

thank you, that makes sense now.

also the length of the first plateau is d as well. I think it will stop on the first plateau, but part b) asks how far it will travel on the plateau, would that be .54*d because of the friction?

d is the height to the top, d/2 is the distance to the first plateau, and the second plateau is on ground level.

d is the height of the entire ramp, as well as the distance across the first plateau. There is no mass, or speed, or angle given. I understand the energy is not conserved, it is lost to friction. That is what is confusing me on finding the distance it will travel across the friction surface.

[SOLVED] conservation of E w/ friction a block is released from rest at height d = 58 cm and slides down a frictionless ramp and onto a first plateau, which has length d and where the coefficient of kinetic friction is 0.54. If the block is still moving, it then slides down a second...
