$!$

Required information

A source$-$free $RC$ circuit has $R=4k,C=22F,$ and $V(O)=1\mathrm{.}000V.$

Calculate the energy stored in the capacitor at $t=0,t=50ms,$ and $t=500ms.$

The energy stored in the capacitor at $t=0,w(t)$ is $J.$

The energy stored in the capacitor at $t=50ms,w(t).$ is $J.($Round the final answer to three decimal places.$)$

The energy stored in the capacitor at $t=500ms,m(t)$ is $$ nJ $.($Round the final answer to three decimal places.$)$
