Chapter 5.2, Problem 5.2GI
In the figure below we’ve replaced one of the hands from Fig. 5.9 with a hook attaching the rope to a wall. On the right, the hand still pulls with a 1-N force. How do the forces now differ from what they were in Fig. 5.9? (a) there’s no difference; (b) the force exerted by the hook is zero; (c) the rope tension is now 0.5 N

In rock climbing, various rope and pulley systems have been devised to help haul up heavy loads, including injured climbers. A rescuer is hauling up an injured climber who weighs 570 NN using the rope and pulley system shown in (Figure 1). (The ropes in this figure are drawn at various angles for clarity, but you can assume they're all vertical.)
What is the tension in rope 1, the rope that the rescuer pulls on?
What is the tension in rope 2?

An 87 kg person stands on a uniform ladder 4.0 m long, that weighs 90 N , as shown in the figure(Figure 1). The floor is rough; hence, it exerts both a normal force, f1, and a frictional force, f2, on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force, f3.
A) Find the forces exerted on the ladder when the person is three-fourths of the way up the ladder.
