Blocks A and B shown in the figure are having equal masses m. The system is released from rest with the spring unstretched. The string between A and ground is cut, when there is maximum extension in the spring. The acceleration of centre of mass of the two blocks at this instant 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 .

In the shown diagram mass of A is m and that of B is 2 m. All the surfaces are smooth. System is released from rest with spring unstretched. Then, the maximum extension (x_(m)) in spring will be:

The system is released from rest with spring intially in its natural length. If mass of the block m = 10 kg. and spring constant k = 100 N//m , then maximum extension in spring is :

The system is released from rest with spring intially in its natural length. If mass of the block m = 10 kg. and spring constant k = 100 N//m , then maximum extension in spring is :

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).

In the figure shown, the system is released from rest with both the springs in unstretched positions. Mass of each block is 1 kg and force constant of each spring is 10 N/m. Maximum speed of the block placed horizontally is:

An ideal spring with spring constant k is hung from the ceiling and a block of mass M is attached to its lower end. The mass is released with the spring initially unstretched. Then the maximum extension in the spring is
