A

`0.44 m//s`

B

`0.88 m//s`

C

`0.20 m//s`

D

`0.15 m//s`

A spring-block system is resting on a frictionless floor as shown in the figure. The spring constant is 2.0 N m^(–1) and the mass of the block is 2.0 kg. Ignore the mass of the spring. Initially the spring is in an unstretched condition. Another block of mass 1.0 kg moving with a speed of 2.0 m s^(–1) collides elastically with the first block. The collision is such that the 2.0 kg block does not hit the wall. The distance, in metres, between the two blocks when the spring returns to its unstretched position for the first time after the collision is _________.

A block of mass m collides with another block of mass 3m completely inelastically as shown in figure. What is the maximum value of v ( in m//s) for which the block B does not move. Assume that initially spring is in natural length and blocks A and B are at rest. (K//m=100 S.I. unit )

A block has a L shaped stand fixed to it. Mass of the block with the stand is M. At the free end of the stand there is a spring which carries a ball of mass m. With the spring in its natural length, the ball is released. It begins to oscillate and the stand is tall enough so that the ball does not hit the block. (a) Find maximum value of mass (m) of the ball for which the block will not lose contact with the ground? (b) If the stand is not tall enough and the ball makes elastic impact with the block, will your answer to part (a) change?

A smooth block of mass m is connected with a spring of stiffness k(=20Nm^(-1) )and natural length l_(0)=0.25 m . If the block is pulled such that the new length of the spring becomes l=0.3m , find the acceleration of the block at the moment when it is released from given positon.

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 :
