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!
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
