Two masses A and B of 3kg and 2kg are connected by a long inextensible string which passes over a mass less and friction less pulley. Initially the height of both the masses from the ground is same and equal to 1 metre. When the masses are released,mass A hits the ground and gets stuck to the ground. Consider the length of the string as large, so that the pulley does not obstruct the motion of masses A and B. [g = 10m/s2]

(A) The impulse A exerts on ground is 6N-S 

(B) The impulse A exerts on ground is 2N-S 

(C) B reaches a maximum height of 2.2 m from the ground. 

(D) B reaches maximum height from the ground 1.2sec after being released.
