Engineering Homework Help

I need help with a program in MatLab. I have developed a code that solves systems of differential equations. He gives me the graph of displacement vs time.

However, I also need the response for acceleration and speed vs time. I would also like the response in frequency domain (Fourier Transform).

Finally, the force that is being used is a sinusoidal force, I would like to exchange it for the acceleration of an earthquake (El centro – Notepad file) plus the white noise (easily found on the internet). (I have a clue on how to do it, but I do not have time. So, if you have any question, feel free to ask me)

Thanks in advance!
