Two small discs of masses `m_1` and `m_2` interconnected by a weightless spring rest on a smooth horizontal plane. The discs are set in motion with initial velocities `v_1` and `v_2` whose directions are mutually perpendicular and lie in a horizontal plane. Find the total energy `overset~E` of this system in the frame of the centre of inertia.
