# Don't look down

A 80 kg climber is standing horizontally on a perfectly vertical cliff face as shown in the picture. The climber is 1.8 meters tall and is attached by a 2-meter-long rope fastened around the climber's middle to a point on the cliff above him. What is the normal force the cliff face exerts on the climber in Newtons?

Details and assumptions

• The climber is not moving.
• The acceleration of gravity is $$-9.8\text{ m/s}^2$$.
• The center of mass of the climber is at the point where the rope meets their body.
