A smooth rubber cord of length `l` whose coefficient of elasticity is k is suspended by one end from the point O (figure). The other end is fittetd with a catch B. A small sleeve A of mass m starts falling from the  point O. Neglecting the masses of the thread and the catch, find the maximum elongation of the cord
