Reconsider Problem 24 but assume \(f_{1}=0\) and \(f_{2}\) is a unit-impulsive force. All parameter values remain unchanged. Assuming zero initial conditions, plot the response \(x_{2}\).

Data From Problem 24:

In the mechanical system in Figure 8.20, the parameter values in consistent physical units are \[m=1, k_{1}=10, k_{2}=10, b_{1}=5, b_{2}=8\]

The system is subject to initial conditions \(x_{1}(0)=0, x_{2}(0)=0, \dot{x}_{1}(0)=-1\) and unit-step applied forces. Plot the response \(x_{1}\).
