Fv = 390 N Sur Previous Answers Mountaineers often use a rope to lower themselves down the face of a cliff (this is called rappelling). They do this with their body nearly horizontal and their feet pushing against the cliff (Eigure 1). Suppose that an 78.6-kg climber, who is 1.88 m tall and has a center of gravity 1.0 m from his feet, rappels down a vertical cliff with his body raised 40.4° above the horizontal. He holds the rope 1.54 m from his feet, and it makes a 20.7° angle with the cliff face. ✓ Correct Part D Figure 1 of 1 What minimum coefficient of static friction is needed to prevent the climber's feet from slipping on the cliff face if he has one foot at a time against the cliff?
