(a) Find the Laplace transform of the waveform $x(t)$ shown in figure.

(b) The network shown in figure is initially under steady state condition with the switch in position $1$. The switch is moved from position $1$ to position $2$ at $t \neq$ 0 . Calculate the current $i(t)$ through $R_1$ after switching.
