An object of mass $\displaystyle 0.2$ kg executes simple harmonic motion along x axis with frequency of $\displaystyle \left(\frac{25}{\pi}\right) \mathrm{Hz}$. At the position $\displaystyle x=0.04 \mathrm{~m}$ the object has kinetic energy $\displaystyle 0.5$ J and potential energy $\displaystyle 0.4$ J . The amplitude of oscillation is $\displaystyle \_\_\_\_$ cm .
