The circuit shown below is in DC steady-state before the switch flips at $t=0\mathrm{s}$. (a) Determine $v_L\left(0^{?}\right)$and $i_L\left(0^{?}\right)$. (b) For $t>0$, determine the zero-state response, $i_{L,ZS}(t)$, the zero-input response, $i_{L,ZI}(t)$ and the full response, $i_L(t)$. (c) For $t>0$, determine $v_L(t)$. (d) Sketch $v_L(t)$ and $i_L(t)$ for $t>?1$, clearly labelling important points.
