Hey guys,

Forgive my ignorance on some of these things. I'm having a bit of trouble understanding the meaning of this question.

In a previous question, the angular acceleration was found to be given by α=mgr/(I+mr^2) where I is the moment of inertia for a disk.

So, question 6, I figure that we would do that by first taking the mean of the set of measured values, and then getting the uncertainty in the mean by (x_max-x_min)/2

However, I'm unsure as to how the dependence would manifest here. I can't seem to find much clear cut info, and it's just leaving me more confused. Am I correct in thinking that the mass is independent, and the angular acceleration is the dependent variable?

If so, how could a linear dependence be expected? I've thought of a few things, such as changing r without changing the mass, but these things don't seem to make sense. I think I've just confused myself to the point that these efforts are futile without external input. Thanks
