Reconsider Problem 22. Plot the response \(x_{2}\) by simulating the Simulink model of the system by using the state-space block.

Data From Problem 22:

The mechanical system in Figure 8.19, where all parameter values are in consistent physical units, is subject to initial conditions \(x_{1}(0)=1, x_{2}(0)=1, \dot{x}_{1}(0)=-1, \dot{x}_{2}(0)=1\). Plot the response \(x_{2}\).
