# Blocks on table!

At a smooth horizontal table are two identical cubes of mass $$m$$, connected by a spring of rigidity $$k$$. The length of spring in the un-stretched state is $$l_0$$. The right cube is linked to the load mass $$m$$ at the end. At some time the system is released and the system moves without initial velocity. Find the maximum distance (in cm) between blocks during the motion of the system.

[$$l_0 = 1 cm$$, $$m = 3 kg$$, $$k = 1000 N/m$$]
