Find the work done by the external agent(a) in compressing the spring by a distance x and (b) bringing the block to its stable equilibrium position.

A block of mass m is slowly lowered from a point where it just touches a vertical fixed spring of stiffness k as shown in figure. They are released from rest. Show that after they have moved a distance L their common speed is given by Two blocks are connected by a string
