To the free end of spring hanging from a rigid support, a block of mass m is hung and slowly allowed to come to its equilibrium position. Then, stretching in the spring is d. If the same block is attached to the same spring and allowed to fall suddenly, the amount of stretching is (force constant k)

An object is attached to a vertical unstretched light spring suspended from a ceiling and slowly lowered to its equilibrium position. This stretches the spring by x. If the same object is attaced to the same vertical spring but permitted to fall suddenly, the spring stretched by
