Two blocks `A(3 kg)` and `B(2 kg)` resting on a smooth horizontal surface is connected by a spring of stiffness `480N//m`. Initially the spring is underformed and a velocity of `2 m//s` is imparted to A along the line of the spring away from B. The maximum extension in meters of the spring during subsequent motion is :-
