A rod of length 2m is maintained to rotate with a constant angular velocity 1 rad s about a vertical axis passing through one end fig There is a spring of spring constant k 1 N m which just encloses rod inside it in natural length One end of the spring is attached to axis of rotation S is a sleeve of mass m 0 4kg which can just fit on the rod All surfaces are smooth With what minimum kinetic energy in J sleeve should be projected so that it enters on the rod without impulse and completely compresses the spring
