How did he get this answer ? \( 7.712 e^{-t} \mathrm{~V} \) for \( 0<t<1 \mathrm{sec} \), \( 4.415 e^{-2(t-1)} \mathrm{V} \) for \( 1 \mathrm{sec}<t<\infty \) Assuming that the switch in Fig. P6.1 has been in position A for a long time and is moved to position \( B \) at \( t=0 \) Then at \( t=1 \) second, the switch moves from \( B \) to \( C \). Find \( v_{c}(t) \) for \( t \geq 0 \). Figure P6.1
