Solution: The period of a simple pendulum is related to the acceleration of gravity as below \begin{align*} T&=2\pi\sqrt{\frac{\ell}{g}}\\\\ 2&=2\pi\sqrt{\frac{\ell}{1.625}}\\\\ (1/\pi)^2 &= \left(\sqrt{\frac{\ell}{1.625}}\right)^2 \\\\ \Rightarrow \ell&=\frac{1.625}{\pi^2}\\\\&=0.17\quad {\rm m}\end{align*} Therefore, a pendulum of length about 17 cm would have a period of 2 s on the moon.
