The circuit in Figure is in the zero state when the step function input is applied.
(a) If VA = 15 V, R = 1.5 kΩ, L = 250 mH, and C = 0.25 μF, derive an expression for the voltage vO(t) for t ≥ 0.
(b) Validate your solution by plotting it using MATLAB and comparing it to a Multisim simulation of the same circuit.
