I am practicing for a mechanics exam.
Please find the problem and solution in the image:
I am not able to reach the solution.
The question is to derivate an expression of the angular speed to obtain the angular acceleration.
The angular speed is a function of the rotation angle, so the problem, I think, it is a differential equation thing. So I tried with all derivation rules (implicit and so on), but I am unable to reach the solution.
How do I derivate that?
Thank you for the help
