The ends of spring are attached to blocks of mass 3 kg and 2 kg. The 3 kg block rests on a horizontal surface and the 2 kg block which is vertically above it is in equilibrium producing a compression of 1 cm of the spring. The 2 kg mass must be compressed further by at least _______ (in mm), so that when it is released, the 3 kg block may be lifted off the ground.
