2. Relevant equations

Find v(t) for t < 0 and t > 0 in the circuit.

3. The attempt at a solution

I tried to find theithrough the inductor for both t=0^{-}and t=infinity, but I did not get the same result as the answer given in the txtbook which is 96e^{-4t}V. According to the answer given from the txtbk, if I'm not wrong, i(t) shud be i(t)=48e^{-4t}A, and then to findvat the 2 ohm resistor, i(t) X 2 and u get v(t).

I do not really understand why, I've been on this qn for 1 hr and stil can't understand it.

Please help and thank you.
