If the above diagram initially there is no elongation in spring if the block is displaced towards right by `x_(0)`. Calculate the elongation of spring A.
.

In the previous problem , the maximum elongation of the spring is

A spring is made of material of Young's modulus 10^(11)N//m^(2) . When a weight of 10 kg is suspended vertically the elongation produced in the spring is 4 mm. If the load is reduced to half the elongation in the spring will be

A block of mass m and relative density y( lt 1) si attached to an ideal spring of constant K. The system is initially at rest and at equilibrium. If the container acceleration upwards with a_(0) , find the increase in the elongation of the spring in equilibrium.

A spring block system is placed on a rough horizontal floor. Force constant of the spring is k. The block is pulled to right to give the spring an elongation equal to x_0 and then it is released. The block moves to left and stops at the position where the spring is relaxed. Calculate the maximum kinetic energy of the block during its motion.

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.

In a vertical spring mass system, a block of mass m is initially at rest when there is no extension. Now if the mass is released suddenly, then the maximum elongation in the spring is

A body of mass m is tied to one end of a spring and whirled round in a horizontal plane with a constant angular velocity and elongation in the spring is 1 cm. If the angular velocity is doubled, the elongation in the spring becomes 5 cm. The original length of spring is

A spring block system is placed on a rough horizontal floor. The block is pulled towards right to give spring some elongation and released.

A block of mass 5 kg having charge q is attached to a spring of constant K = 10^(4) N//m . A charge -q is placed below the block at separation 0.5 m . If the maximum elongation of spring is 0.5 m . If the maximum elongation of spring is 0.1 m , find q . Assume the initial elongation of spring is zero.
