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

The block shown in figure is released from rest. Find out the speed of the block when the spring is compressed by 1 m

An elastic spring is compressed between two blocks of masses 1 kg and 2 kg resting on a smooth horizontal table as shown. If the spring has 12 J of energy and suddenly released, the velocity with which the larger block of 2 kg moves will be .

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 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,

Initially spring is compressed by x_(0) and blocks are in contact when system is released, then block starts moving and after some time contact between blocks, then

Initially spring is compressed by x_(0) and blocks are in contact when system is released, then block starts moving and after some time contact between blocks, then

One end of spring of force constant k is fixed to a vertical wall and the other to a block of mass m resting on a smooth horizontal surface. There is another wall at a distance, x_(0) from the block . The spring is then compressed by 2x_(0) and released. The time taken by the block to strike the other wall is

A small block of mass m is fixed at upper end of a massive vertical spring of spring constant k=(2mg)/(L) and natural length 10L The lower end of spring is free and is at a height L from fixed horizontal floor as shown. The spring is initially unstressed and the spring block system is released from rest in the shown position. Q. Till the blocks reaches its lowest position for the first time, the time duration for which the spring remains compressed is
