The top of an elastic rope (whose length can change) is fixed on the wall at theheight of 3 meters to the ground. Suppose the bottom end of the rope on the ground is dragged away from the wall at a constant velocity of 5 meters per second. The rope will break when the rate of change of its length reaches 4 meters per second. Find the distance between the bottom end of the rope and the wall at the moment when it breaks.
