Allow me to simplify my question:
Regadless or what the shapes are, regardless of any expected values,
Don't objects traveling down the ramp with higher Acceleration...If you plug that in, to solve for moment of Inertia,doesn't higher acceleration give you a LOWER number in front of MR^2...
Like I said, objects with the higher acceleration are giving me the lowest values. For a hoop, I got I=0.1*MR^2
For a cylinder, I got I=0.7*MR^2
this seems backwards, no?
