Question

Please use second order circuit formula to solve.

Need V0 = capasitor initial voltage        and I0 = Inductor initial current

alpha = 1/2RC = 250,      w0= sqrt(1/LC) = 250 so criticalli damped responce

i(t)=D1te^-alpha t +D2e^-alpha t

 equuation with alpha in it  is: i(t)=D1te^-250t +D2e^-250t

2 simultaneous equations to solve for D1 and D2 are:

D2=I0

D1-250D2=di/dt                           using formula v=Ldi/dt         di/dt=V/L
