Two climbers are on a mountain. Simon, of mass m, is sitting on a snow covered slope that makes an angle θ with the horizontal. The coefficient of static friction between his body and the snow is μ. He is tied into one end of a massless rope that runs over a frictionless pulley. Joe, of mass M, is at the other end of the rope. He has fallen and is hanging motionless below an overhang. Derive an expression for the maximum value of Joe's mass M so that Simon is not pulled down the slope, in terms of relevant system parameters.

If almost any system in stable equilibrium is slightly disturbed, it will then exhibit simple harmonic motion because 1. the change in potential energy is proportional to the cube of the displacement from the equilibrium position. 2. the change in potential energy is proportional to the square of the displacement from the equilibrium position. 3. the force on a system in unstable equilibrium is zero. 4. the kinetic energy on a system in stable equilibrium is zero. 5. mechanical energy is conserved. 6. momentum is conserved. 7. the force on a system in stable equilibrium is zero. 8. the momentum of a system in stable equilibrium is zero. 9. momentum and mechanical energy are both conserved. 10. the change in potential energy is proportional to the displacement from the equilibrium position.
