I was wondering if someone can help me solve a problem of kirchoff's law using maple, heres the problem:

Use maple and Laplace transform to find the charge q(t) on the capacitor in an RC series circuit with the following conditions; graph q(t) on the interval 0<t<6 and use the graph to estimate the time and value of the maximum charge

q(0)=0
R=50 ohms
C=.01 farads
E is a piecewise where 1<x<3 = 100, everywhere else is zero
I'm assuming that since nothing is said about the inductance in the initial conditions, L=0

heres what i got so far:

>i(t):= diff(q(t),t);
>KirchoffLaw:=E[R]+E[L]+E[C]-E[emf]=0;
