An ideal spring is permanently connected between two blocks of masses `M` and `m`. The blocks-spring system can move over a smooth horizontal table along a straight line along the length of the spring as shown in Fig.The blocks are brought nearer to compress the spring and then released. In the subsequent motion,

A light spring of force constant 'K' is held between two blocks of masses 'm' and '2m'. The two blocks and the spring system rests on a smooth horizontal floor. Now th blocks are moved towards each other compressing the springs by 'x' and suddenly released. The relative velocity between the blocks when the spring attains its natural length will be

Two blocks are connected to the two free ends of a spring of spring constant K . Both the blocks are moved apart to extend the psring beyond its natural length and then released . In subsequent motion

Two blocks of masses m and M connected by a light spring of stiffness k, are kept on a smooth horizontal surface as shown in figure. What should be the initial compression of the spring so that the system will be about to break off the surface, after releasing the block m_1 ?

A block attached with an ideal spring is kept on a smooth horizontal surface. Now the free end of the spring is pulled with a constant velocity u horizontally. Then the maximum energy stored in the spring and bock system during subsequent motion is :

An ideal spring is compressed and placed horizontally between a vertical fixed wall and a block free to slide over a smooth horizontal table to as shown in the figure. The system is released from rest. The graph which represents the relation between the magnitude of acceleration a of the block and the distance x travelled by it (as long as the spring is compressed) is
