A simple harmonic oscillator has an amplitude $\displaystyle A$ and time period $\displaystyle 6 \pi$ second. Assuming the oscillation starts from its mean position, the time required by it to travel from $\displaystyle x=\mathrm{A}$ to $\displaystyle x=\frac{\sqrt{3}}{2} \mathrm{~A}$ will be $\displaystyle \frac{\pi}{x} \mathrm{~s}$, where $\displaystyle x=$ $\displaystyle \_\_\_\_$.
