But isn't there still going to be some amount of friction between the wheels and the belt, even with a constant velocity. With zero belt acceleration there must still be some force on the string. If there wasn't the cart would remain stationary wrt the ground even if we changed the belt velocity...
I get
f= [ g'(t) I ] / [r^2]
now am I correct in saying that g'(t) would be considered the acceleration of the belt? I don't believe that this statement is correct seeing as that would mean that there would be no tension on the rope if the belt is moving at a constant velocity.
Now if...
Just came across this. Check out this picture taken by a guy who flew his plane to the North Pole in July of 2011. For the record...I think he is nuts!

Hi there! First off, I am new to these forums so be nice! The question I have isn't homework, but rather personal curiosity.
Homework Statement
Imagine that you have some type of cart on a conveyer belt. The cart is held stationary with respect to the world by a rope. The conveyer belt...
