A solid, uniform cylindrical buoy of total height \(H\), cross-sectional area \(A\), and uniform density \(\rho_b\) floats upright in a liquid of density \(\rho\), where \(\rho > \rho_b\). The buoy is depressed vertically downward by a small distance from its static equilibrium position and released from rest at time \(t = 0\). Assuming the liquid is inviscid and resistive drag is negligible, what is the frequency \(f\) of the resulting vertical simple harmonic oscillations of the buoy?
