The circuit in Figure P7-4 8 is in the zero state when the step function input is applied.

(a) If \(V_{\mathrm{A}}=15 \mathrm{~V}, R=1.5 \mathrm{k} \Omega, L=250 \mathrm{mH}\), and \(C=025 \mu \mathrm{F}\), derive an expression for the voltage \(v_{\mathrm{O}}(t)\) for \(t \geq 0\).
(b) Validate your solution by plotting it using MATLAB and comparing it to a Multisim simulation of the same circuit.
