1. The problem statement, all variables and given/known data

Hello, I have the following task:

2. Relevant equations

3. The attempt at a solution

I looked at this task with the notes from the class, but I can't really see through. It seems that the first step is the transformation into the single decoupled second order differential equation, but I don't actually understand how to do that and at which point I need a program to solve it. Can someone guide me through the solution process?

Write the two equations for $\dot{c}_0$ and $\dot{c}_1$ and derive both sides with respect to time. It shouldn't be too hard to see then how to obtain the two uncoupled equations.

Hello,
thank you for helping me.

I tried to do that and obtained the following:

If this is correct, I still don't see what I have to do in the next step and when I have to use a program.
