# Mr. Doppler in a circle

**Classical Mechanics**Level 4

A tuning fork is moving in clockwise direction on a circle centered at origin of radius \(\sqrt { 2 }m\) with speed \(125m/s\). Find the coordinates \((a,b)\) of the tuning fork when the stationary observer at \((1,3)\) hears maximum frequency.

Select \({a}^{6}+{b}^{6}\).
