Find vcnbspt and ilt for t ge 0- is the circuit overdamped

Question

The switch in given Figure has been in position A for a long time. At t = 0 it is moved to position B. The circuit parameters are R₁ = 20 kΩ, R₂ =4kΩ, L = 1.6 H, C = 1.25 μF, and V_A = 24 V.

(a) Find v_C (t) and i_L(t) for t ≥ 0.

(b) Is the circuit overdamped, critically damped, or underdamped? (c) Use Multisim to validate your results.
