I have this number where they give me the coordinates of 3 particles and the mass of each one of them. Afterwards, there's a force applied on 2 of those particles and they ask me to calculate the systems total moment of inertia. But then they ask me this:

If the system goes from rest and that the forces from c) are applied for 5 seconds and after that 5 seconds no more forces are exerted, how much time does the system take to perform one full rotation.

So I think I'll find the answer using

T = 2pie/w, where I'll find w by first finding my angular acceleration a = t/I

from where I can find w using w = at. Then I solve for T in the first one.

is that correct?
