A cord is wrapped onto a cylindrical reel mounted on a fixed frictionless horizontal
axle. When does the reel have a greater magnitude of
angular acceleration?
1. When the cord is pulled down with
a constant force of 50 N.
2. When an object of weight 50 N is
hung from the cord and released.
3. The angular accelerations in parts
(a) and (b) are equal.
4. It is impossible to determine.​
