Question

As shown in the figure below, 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? When the cord is pulled down with a constant force of 50 N When an object of weight 50 N is hung from the cord and released.      The angular accelerations in parts (a) and (b) are equal. It is impossible to determine.
