Consider the 65.0 kg mountain climber in the figure.

(a) Find the tension in the rope (in N) and the force that the mountain climber must exert with her feet (in N) 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.

tension in rope N:

force on feet N:

(b) What is the minimum coefficient of friction between her shoes and the cliff?

Step 1

a)

The balancing force along vertical and horizontal direction is,

Step 2

Solving equation (I) and (II), the required tension in the rope is,

Step 3

From equation (II), the required fo...
