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

Two blocks of masses 1 kg and 2 kg are placed in contact on a smooth horizontal surface as shown in fig. A horizontal force of 6N is applied d(a) on a 1-kg block. Find the force of interaction of the blocks. .

Two blocks of masses m and m' are connected by a light spring on a horizontal frictionless table . The spring is compressed and then released . Find the ratio of acceleration of masses .

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

Three block of masses 1kg,4 kg and 2 kg are placed on a smooth horizontal plane as shown in figure. Find (a) the acceleration of the system, (b) the normal force between 1kg block and 4 kg block, ( c) the net force on 2kg block

A spring of force constant k = 300 N/m connects two blocks having masses 2 kg and 3kg lying on a smooth horizontal plane. If the spring block system is released from a stretched position find the number of complete oscillations in 1 minute. Take pi = sqrt10

Two blocks of masses 4kg and 2kg are placed side on a smooth horizontal surface as shown in the figure. A horizontal force of 20N is applied on 4kg block. Find (a) the acceleration of each block. (b) the normal reaction between two blocks.

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

Two blocks of masses 1 kg and 3 kg are moving with velocities 2 m//s and 1 m//s , respectively , as shown. If the spring constant is 75 N//m , the maximum compression of the spring is
