In the above problem if block is released from there, what would be maximum extension.

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

Energy released per gram would be

In the above problem, direction of friction force is

In the adjoining figure, block A is of mass (m) and block B is of mass 2m. The spring has force constant k. All the surfaces are smooth and the system is released form rest with spring unstretched. Find the maximum extension in the spring and acceleration of block B at time of maximum extension .

A block of mass 1kg is kept on the tilted floor of a lift moving down with acceleration 3ms^(-2) . If the block is released from rest as shown, what will be the time taken by block to reach the bottom? What is the normal reaction on the block during the motion?

In the above problem, the maximum positive displacement x is

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 the above problem, find the distances of fourth maxima from 'O'.

Consider the situation shown in figure. Mass of block A is m and that of blcok B is 2m. The force constant of string is k. Friction is absent everywhere. System is released from rest with the spring unstretched. Find (a) The maximum extension of the spring x_(m) (b) The speed of block A when the extension in the springt is x=(x_(m))/(2) (c ) The net acceleration of block B when extension in the spring is x=(x_(m))/(4).

A block of mass m attached with a an ideal spring of force constant k is placed on a rough inclined plane having inclination theta with the horizontal and coefficient of friction mu=1//2 tan theta , Initially the block is held stationary with the spring in its relaxed state, find the maximum extension in the spring if the block is released.
