Consider the system described by the following state space representation
$\begin{bmatrix}
\dot{x}_{1}(t)\\
\dot{x}_{2}(t)
\end{bmatrix}=\begin{bmatrix}
0 &1 \\
0 & -2
\end{bmatrix}
\begin{bmatrix}
{x}_{1}(t)\\
{x}_{2}(t)
\end{bmatrix}+\begin{bmatrix}
0\\
1
\end{bmatrix} u(t)$
$y(t)=\begin{bmatrix}
1 & 0
\end{bmatrix}\begin{bmatrix}
{x}_{1}(t)\\
{x}_{2}(t)
\end{bmatrix}$
If $u(t)$ is a unit step input and $\begin{bmatrix}
{x}_{1}(0)\\
{x}_{2}(0)
\end{bmatrix}=\begin{bmatrix}
1\\
0
\end{bmatrix}$, the value of output $y(t)$ at $t=1$ sec (rounded off to three decimal places) is ___________.
