Consider the 52.0-kg mountain climber shown below. (a) Find the tension in the rope and the force that the mountain climber must exert with her feet on the vertical rock face
to remain stationary. Assume that the force is exerted parallel to her legs. Also, assume
negligible force exerted by her arms. (b) What is the minimum coefficient of friction
between her shoes and the cliff?
