The transfer function of a mass-spring-damper system is given by $$G(S) = \dfrac{1}{Ms^{2}+Bs+K}$$

The frequency response data for the system are given in the following table.

$\begin{array}{|l|l|l|} \hline \omega \text{ in rad/s} & \mid G( j \omega) \mid \text{in dB} & \text{arg } (G(jw)) \text{in deg} \\ \hline 0.01 & -18.5 & -0.2 \\ \hline 0.1 & -18.5 & -1.3 \\ \hline 0.2 & -18.4 & -2.6 \\ \hline 1 & -16 & -16.9 \\ \hline 2 & -11.4 & -89.4 \\ \hline 3 & -21.5 & -151 \\ \hline 5 & -32.8 & -167 \\ \hline 10 & -45.3 & -174.5 \\ \hline \end{array}$

The unit step response of the system approaches a steady state value of ________.
