Rough seas cause a ship to heave with an amplitude of \(0.4 \mathrm{~m}\) at a frequency of \(20 \mathrm{rad} / \mathrm{s}\). Design an isolation system with a damping ratio of 0.13 such that a \(45 \mathrm{~kg}\) navigational computer is subject to an acceleration of only \(20 \mathrm{~m} / \mathrm{s}^{2}\).
