A block of mass `m` is at rest on an another block of same as shown in figure lower block is atteched to the spring than the maximum amplitude of motion as than both the block will remain as mat both the block will remain in contact is

A block of mass m is at rest on the another blcok of same mass as shown in figure. Lower block is attached to the spring then the maximum amplitude of motion so that both the blcok will remain in contact is

A block of mass m is at rest on the another blcok of same mass as shown in figure. Lower block is attached to the spring then the maximum amplitude of motion so that both the blcok will remain in contact is

A block of mass m compresses a spring iof stifffness k through a distacne l//2 as shown in the figure .If the block is not fixed to the spring the period of motion of the block is

A block of mass m is placed on the top of another block of mass M as shown in the figure. The coefficient of friction between them is mu . The maximum acceleration with which the block M may move so that m also moves along with it is

A block of mass 4 kg is placed on another block of mass 5 kg and the block B rests on a smooth horizontal table. If the maximum force that can be applied on A so that both the blocks move together is 12N, find the maximum force that can be applied on B for the blocks to move together.

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 )

Two blocks of masses m_(1) and m_(2) are kept on a smooth horizontal table as shown in figure. Block of mass m_(1) (but not m_(2) is fastened to the spring. If now both the blocks are pushed to the left so that the spring is compressed a distance d. The amplitude of oscillatin of block of mass m_(1) after the system is released is
