What tension does his rope need to support? 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 (Figure 1). Suppose that an 77.6-kg climber, who is 1.97 m tall and has a center of gravity 1.1 m from his feet, rappels down a vertical cliff with his body raised 41.6° above the horizontal. He holds the rope 1.56 m from his feet, and it makes a 24.4" angle with the clif face. Express your answer using two significant figures. IVO AE d p ) ?
