A block of mass `m` held touching the upper end of a light spring of force constant K as shown in figure. Find the maximum potential energy stored in the spring if the block is released suddenly on the spring.

A block of mass m is suspended by different springs of force constant shown in figure.

A block of mass m moving at a speed v_0 compresses a spring of spring constant k as shown in the figure. Find (a) the maximum compression of spring and (b) speed of the block when the spring is compressed to half of maximum compression.

The block of mass m is released when the spring was in its natrual length. Spring constant is k. Find the maximum elongation of the spring.

The block of mass m is released when the spring was in its natrual length. Spring constant is k. Find the maximum elongation of the spring.

In figure, the stiffness of the spring is k and mass of the block is m . The pulley is fixed. Initially, the block m is held such that the elongation in the spring is zero and then released from rest. Find: a. the maximum elongation in the spring. b. the maximum speed of the block m . Neglect the mass of the spring and that of the string. Also neglect the friction.
