Block A is hanging from vertical spring of spring constant K and is rest. Block B strikes block A with velocity v and sticks to it. Then the value of v for which the spring just attains natural length is

A block A of mass 2m is hanging from a vertical massless spring of spring constant k and is in equilibrium. Another block B of mass m strikes the block A with velocity u and sticks to it as shown in the figure. The magnitude of the acceleration of the combined system of the blocks just after the collision is

Two blocks A and B of masses in and 2m , respectively, are connected with the help of a spring having spring constant, k as shown in Fig. Initially, both the blocks arc moving with same velocity v on a smooth horizontal plane with the spring in its natural length. During their course of motion, block B makes an inelastic collision with block C of mass m which is initially at rest. The coefficient of restitution for the collision is 1//2 . The maximum compression in the spring is

A block of mass m, attacted to a string of spring constant k, oscillates on a smooth horizontal table. The other end of the spring is fixed to a wall. The block has a speed v when the spring is at its natural length. Before coming to an instantaneous rest. If the block moves a distance x from the mean position, then

Two blocks A and B . each of mass m , are connected by a massless spring of natural length I . and spring constant K . The blocks are initially resting in a smooth horizontal floor with the spring at its natural length, as shown in Fig. A third identical block C , also of mass m , moves on the floor with a speed v along the line joining A and B . and collides elastically with A . Then

A block of mass 2kg is attached with a spring of spring constant 4000Nm^-1 and the system is kept on smooth horizontal table. The other end of the spring is attached with a wall. Initially spring is stretched by 5cm from its natural position and the block is at rest. Now suddenly an impulse of 4kg-ms^-1 is given to the block towards the wall. Find the velocity of the block when spring acquires its natural length

Assertion: Two blocks A and B are connected at the two ends of an ideal spring as shwon in figure. Initially, spring was released. Now block B is pressed. Linear momentum of the system will not remain constan till the spring reaches its initial natural length. Reason: An external force will act from the wall on block A.

The arrangement shown in figure is at rest. An ideal spring of natural length l_0 having spring constant k=220Nm^-1 , is connected to block A. Blocks A and B are connected by an ideal string passing through a friction less pulley. The mass of each block A and B is equal to m=2kg when the spring was in natural length, the whole system is given an acceleration veca as shown. If coefficient of friction of both surfaces is mu=0.25 , then find the maximum extension in 10(m) of the spring. (g=10ms^-2) .

Two block A and B of masses m and 2m respectively are connected by a spring of spring cosntant k. The masses are moving to the right with a uniform velocity v_(0) each, the heavier mass leading the lighter one. The spring is of natural length during this motion. Block B collides head on with a thrid block C of mass 2m . at rest, the collision being completely inelastic. The velocity of block B just after collision is -

A system consists of block A and B each of mass m connected by a light spring as shown in the figure with block B in contact with a wall. The block A compresses the spring by 3mg/k from natural length of spring and then released from rest. Neglect friction anywhere. Velocity of centre of mass of system comprising A and B when block B just loses contact with the wall
