HAHA! Oh man, thank you for pointing out the key flaw.. :) This is to describe the breaking of a piece of toilet paper off the roll. I have read the other post on the site, but it wasnt heavily equation laden. Thanks!

Here is how I derived angular acceleration to linear acceleration: > Radius*theta = ArcLength; > d(Radius*theta)/dt = ds/dt; > Radius*omega = V; > d(Radius*omega)/dt = dV/dt; > Radius*alpha = a; > alpha = a/Radius; here is a link for a clearer image...

My main confusion is in the proof my professor showed us just before break. He came up with a relationship of (angular acceleration)=radius*(linear acceleration) which doesn't make sense, we are assuming a 90 degree angle, so from r x (angular acceleration) = (linear acceleration) wouldn't we...
