Two disks of masses `m_(1)` and `m_(2)` are connected by a spring of force canstant k. The lower disk of mass `m_(2)`lies on a table and the upper disk is vertically above it. What vertical force F should be applied to the upper disk so that when the force is withdraw, the lower disk is lifted off the table?

A disc of mass m_(2) is placed on a table. A stiff spring is attached to it and is vertical. The other end of the spring is attached to a disc of mass m_(1) What minimum force should be applied to the upper disc to press the spring such that the lower disc is lifted off the table when the external force is suddenly removed?
