A block is attached to a spring as shown and very-very gradually lowered so that finally spring expands by 'd'. If same block is attached to spring and released suddenly then maximum expansion in spring will be

Force constant of a spring is 100 N//m . If a 10kg block attached with the spring is at rest, then find extension in the spring. ( g= 10 m//s^(2) )

A block of mass m attached with a spring and held by a person such that the spring is in natural length l_(0) . Now the man releases the block, the ratio of maximum compression in the spring in the given situation , to that of the compression at equilibrium position.

A block of mass 'm' is attached to a spring in natural length of spring constant 'k' . The other end A of the spring is moved with a constat velocity v away from the block . Find the maximum extension in the spring.

A block is released from height h , find the maximum compression of spring of spring constant k .

Block A of mass m is placed on a plank B . A light support S is fixed on plank B and is attached with the block A with a spring of spring constant K . Consider that initially spring is in its natural length. If the plank B is given an acceleration a, then maximum compression in the spring is (xma)/(k) . Find the value of x (All the surface are smooth)

Block is attached to system of springs. Calculate equivalent spring constant. .

An ideal spring with spring constant k is hung from the ceiling and a block of mass M is attached to its lower end. The mass is released with the spring initially unstretched. Then the maximum extension in the spring is

An ideal spring with spring - constant K is bung from the colling and a block of mass M is attached to its lower end the mass is released with the spring initally unstetched . Then the maximum exlemsion in the spring is

An object is attached to a vertical springs and lowered slowly to its equilibrium position. This stretches the spring by a distance d . If the same object is attached to the same vertical spring, but permitted to fall freely, through what distance does it stretch the spring ?
