7–54 The switch in Figure P7–54 has been open for a long time and is closed at t = 0. The circuit parameters are L=1H, C = 0:5 μF, R= 100 Ω, and vCð0Þ = 5 V.

(a) Find vCðtÞ and iLðtÞ for t ≥ 0.

(b) Is the circuit overdamped, critically damped, or underdamped?

(c) Use Multisim to simulate your results.
