A desperate hiker has to think fast to help his friend who has fallen below him. Quickly, he ties a rope to a rock of mA = 405 kg and makes his way over the ledge (see the figure below). If the coefficient of static friction between the rock and the ground is H=0.348, and the mass of the hiker is ma= 70.1 kg, what is the maximum mass of the friend, mc, that the rock can hold so the hikers can then make their way up over the ledge? Assume the rope is parallel to the ground and the point where the rope passes over the ledge is frictionless. (ANS: 70.8 kg)

We are going to create a model for the forces acting when climbing with mass 'm' while falling on a rope. To simplify the problem, we will assume that there is no external or internal friction on the rope, and that there is no slack in the rope when the climber falls a height 'h/2' above the last belay, as shown in Figure. The rope has a length 'L' (in meters) when the fall occurs. All movement in the model is vertical (along the y-axis), and we will assume that the positive direction is downward. In part (a), the climber is in free fall until the rope starts to catch the fall. Set up the model for free fall and derive the expression for the velocity v0 that the climber has when the rope starts to slow down the fall. You can assume that the climber's speed is only a function of 'y' such that dy/dt = v(y)⟹ d²v/dt² = v * dv/dy

A 1520-N crate is to be held in place on a ramp that rises at 30.0° above the horizontal (see figure). The massless rope attached to the crate makes a 22.0° angle above the surface of the ramp.

A desperate hiker has to think fast to help his friend who has fallen below him. Quickly, he ties a rope to a rock of mass ma and makes his way over the ledge (see the figure).
