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.

A body of mass m hangs by an inextensible string that passes over a smooth mass less pulley that is fitted with a light spring of stiffness k as shown in figure. If the body is released from rest and the spring is released, calculate the maximum elongation of the spring.

A block of mass m is attached with a spring in vertical plane as shown in the figure. If initially spring is in its natural length and the block is released from rest, then maximum extension in the spring will be

Two blocks of masses m_(1) = 2kg and m_(2) = 4kg are attached to two ends of a light ideal spring of force constant k = 1000 N // m. The system is kept on a smooth inclined plane inclined at 30^(@) with horizontal. The block m_(2) is attached to a light string whose other end is connected to a mass m_(3) = 1 kg . A force F = 15N is applied on m_(1) and the system is released from rest. Assume initially the spring is at relaxed position and the system is released from rest. Find the (a) maximum extension of the spring. (

A system of wedge and block as shown in figure, is released with the spring in its natural length. All surfaces are frictionless. Maximum elongation in the spring will be .

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.

Two springs are in a series combination and are attached to a block of mass 'm' which is in equilibrium. The spring constants and extension in the springs are as shown in the figure. Then the force exerted by the spring on the block is :
