The unit impulse response of a linear time-invariant second order system is; \(g(t)=10 e^{-8 t} \sin\) \(6 t(t<0)\). The natural frequency and the damping factor of the system are respectively:
(a) \(10 \mathrm{rad} / \mathrm{s}\) and 0.6
(b) \(10 \mathrm{rad} / \mathrm{s}\) and 0.8
(c) \(6 \mathrm{rad} / \mathrm{s}\) and 0.6
(d) \(6 \mathrm{rad} / \mathrm{s}\) and 0.8
