Question

Two identical blocks $A$ and $B$ each of mass $2 k g$ are hanging stationary by a light inextensible flexible string, passing over a light and frictionless pulley, as shown in Fig. A shell $C$ of mass $1 k g$ moving vertically upwards with velocity $9 m / s$ collides with block $B$ and gets stuck to it.

Calculate the time after which block $B$ starts moving downwards.
