Use Simulink to construct block diagrams to find the displacement output \(x(t)\) of the system subjected to an applied force \(f(t)=10 u(t)\), where \(u(t)\) is the unit-step function. The parameter values are \(m=1 \mathrm{~kg}, b=2 \mathrm{~N} \cdot \mathrm{s} / \mathrm{m}\), and \(k=5 \mathrm{~N} / \mathrm{m}\). Assume zero initial conditions.
