The oscillation frequency of the wing tips is $2.5~Hz$
We can find the angular frequency $\omega$: $a_m = A~\omega^2$ $\omega = \sqrt{\frac{a_m}{A}}$ $\omega = \sqrt{\frac{12~m/s^2}{0.050~m}}$ $\omega = 15.49~rad/s$ We can find the oscillation frequency: $2\pi~f = \omega$ $f = \frac{\omega}{2\pi}$ $f = \frac{15.49~rad/s}{2\pi}$ $f = 2.5~Hz$ The oscillation frequency of the wing tips is $2.5~Hz$.
