I think it may be easier to post my work than trying to explain it. This is what I have done, and I am unsure where my error may be. Any help is greatly appreciated!

But once you find the inertia what would you do from there?

They don't give it to you in the problem. Would I calculate the inertia on each disk and add those together to get the total inertia of the disk system?

Problem Solved! I found the solution, I used the centripetal force equation like I explained above, but I did not divide by 2 at the end. Fc=mv2/r v=√(Fcr/m) v=√[(3.6 N)(0.38 m)/(0.0012kg)] v=33.76388603 m/s v=38 m/s
