A block of mass `'m'` is hanging from a massless spring of spring constant `K`. It is in equilibrium under the influence of gravitational force. Another particle of same mass `'m'` moving upwards with velocity ao hits the block and sticks to it. For the subsequent motion, choose the incorrect statements:

A block of mass m suspended from a spring of spring constant k . Find the amplitude of S.H.M.

A block of mass m suspended from a spring of spring constant k . Find the amplitude of S.H.M.

A block of mass m suspended from a spring of spring constant k . Find the amplitude of S.H.M.

A block of mass m hangs from a vertical spring of spring constant k. If it is displaced from its equilibrium position, find the time period of oscillations.

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
