The follower circuit in Figure P7-20 is in the zero state and (R_{1}=50 mathrm{k} Omega, R_{2}=2 mathrm{k}

Question:

The follower circuit in Figure P7-20 is in the zero state and $R_{1}=50 \mathrm{k} \Omega, R_{2}=2 \mathrm{k} \Omega$, and $C=0.1 \mu \mathrm{F}$.
(a) Suppose $v_{\mathrm{S}}(t)=2 u(t)$, find $v_{2}(t)$ for $t \geq 0$.
(b) Suppose $v_{\mathrm{S}}(t)=2 e^{-5000 t} u(t)$, find $v_{2}(t)$ for $t \geq 0$.
(c) Repeat (b) using Multisim.
