REMARKS Proper handling of signs is very important in these problems. All such signs should be chosen
intially and checked mathematically and physically. In this problem, for example, both the angular
acceleration $\alpha$ and the acceleration $a$ are negative, so $\alpha = a/R$ applies. If the rope had been wound the
other way on the cylinder, causing counterclockwise rotation, the torque would have been positive, and the
relationship would have been $\alpha = -a/R$, with the double negative maling the right-hand side positive,
Just like the left hand side.
QUESTION How would the acceleration and tension change if most of the reel's mass were at its rim?
(Select all that apply.)
The acceleration would decrease.
The acceleration would increase.
The tension $T$ would increase.
The tension $T$ would remain the same.
The acceleration would remain the same.
The tension $T$ would decrease.
