Urgent help needed regarding solving differential equations involving fft

Hii Friends,

I am almost a beginner in matlab and need to solve the equations shown in the pic for an assignment.

Can anyone advice me or depict an example to solve the equations.

The second equation has fft and inverse fft(indicated by F) along with differential equations.

Scratching my head out. Your help is highly appreciated.

Thanking you in advance.

Pavan

Do you want to solve this numerically or symbolically? The tag "ode45" sounds like a numerical solution, but it would be better if you mention this explicitely. What have you tried so far? What exactly is the problem?

Please read and consider https://www.mathworks.com/matlabcentral/answers/29922-why-your-question-is-not-urgent-or-an-emergency. The term "urgent" discurages me and some others to post an answer.
