At $\mathrm{t}=0$, the lower end of the bar A is just above the upper end of bar B (mass of bar $\mathrm{B}=3\mathrm{kg}$, mass of bar A $=\frac{11}{3}\mathrm{kg}$ ). Find time (in sec) when upper end of block $A$ just crosses the lower end of $B$. (Assume the system was released at $\mathrm{t}=0).\left[\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2\right]$
