A system model and its inputs and outputs are provided. Find the appropriate transfer function or matrix.

\(\left\{\begin{array}{l}\ddot{q}_{1}+\dot{q}_{1}+\frac{1}{2}\left(q_{1}-q_{2}\right)+q_{1}=v(t) \\ \dot{q}_{2}-\frac{1}{2}\left(q_{1}-q_{2}\right)=0\end{array}, v(t)=\right.\) input, \(q_{1}=\) output
