A bob of mass `2m` hanges by a string attached to the block of mass `m` of a spring blocks syetem. The whole arrangement is in a state of equilibrium. The bob of mass `2m` is pulled down slowely by a distance `x_(0)` and released.

The block of mass m_1 shown in figure is fastened to the spring and the block of mass m_2 is placed as against it. Find the compression of the spring in the equilibrium position.

As shown in figure pulley is ideal and strings are massless.If mass m of hanging block is the minimum mass to set the equilibrium of system, then -

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

As shown in the figure, two bobs of masses m & 2m are tied by a massless string which is wound on a fly wheel (disc) of radius r and mass m. When released from rest the bob of mass 2m starts falling vertically. When it has covered distance of h, the angular speed of the wheel will be:
