A block of mass m is attached to the light spring of force constant k and released when it is in its natural length. Find amplitude of subsequent oscillations.

A block of mass m is attached to the light spring of force constant k

1.	A block of mass m is attached to the light spring of force constant k and released when it is in its natural length. Find amplitude of subsequent oscillations.
Answer» Solution :The maximum displacement of the spring in SUBSEQUENT motion will be `(2mg)/(k)` The equilibrium position of the SYSTEM will OCCUR at the extension of `(MG)/k` `therefore ` AMPLITUDE `=(2mg)/(k) - (mg)/(k) = (mg)/(k)`
