A Z-Drag is an arrangement of ropes in pulleys often used in rescue situations. Implemented properly, it can multiply a rescuer's input force by a factor of 3. Suppose a rescuer uses an ideal Z-Drag system to pull a wrapped river raft off of a rock. The rescuer pulls on the rope with a force of 300 N and the rope moves a total distance of 3 meters on the rescuer's end. What is the force on the raft? How far will the raft move?
