Задача id12752

A load A was attached to the end of a vertically hanging spring of length l, as a result of which its length increased to 2l. Assuming that the elongation of the spring is proportional to the load, find the angular velocity of the load A rotating on this spring in a circle in the horizontal plane (Fig. 60), if the length of the spring in this case is L. Neglect the mass of the spring.
