A thin uniform $\displaystyle \operatorname{rod}(X)$ of mass $\displaystyle M$ and length $\displaystyle L$ is pivoted at a height $\displaystyle \left(\frac{L}{3}\right)$ as shown in the figure. The rod is allowed to fall from a vertical position and lie horizontally on the table. The angular velocity of this rod when it hits the table top, is $\displaystyle \_\_\_\_$.
(g = gravitational acceleration)
