Circuits Question -- Voltage and current in an inductor circuit

1. The problem statement, all variables and given/known data

See Attached

2. Relevant equations

3. The attempt at a solution

I found Zeq and there are exactly 2 Amps going into it. I'm not sure what to do from here.

$Z_{eq} = \frac{<(arctan(\frac{R}{ωL}))}{ω^{2}L^{2}+R^{2}}$

I'm not sure what to do from here, thanks for any help.

Re: Circuits Question

Ok so because this is DC

ω = 2∏f

but f= 0

so

$Z_{eq} = \frac{j}{R^{2}}$

Where do I go from here?

vL(t) = 120e-2500t

iL(t) = 2 + 6e-2500t
