Moment of Inertia

Can we say that I is mv^2 in our explanation or should we try and find the most accurate equation for the situation?

Do you mean I = mR^2? If so, that is the moment of inertia for a point. They should provide you with the moments of inertia for all the different shapes, so you’ll be expected to pick the right one.

A quick note like “I_{disk} = \frac{1}{2}mR^2” if the problem has a disk would definitely be a good idea for grading clarity.
