A load weighing P = 100 n is tied to the freely hanging end of a rope wound on a winch. Both the load and the winch are at a certain height. The load begins to fall, and the rope became tense when the load flew h = 12 m. After this, they began to slow down the movement of the load using a winch. What is the minimum length l of the rope that had to be pulled out before the load stops completely, if the strength of the rope is T = 180 n?
