As shown in Figure OQ10.7, a cord is wrapped onto acylindrical reel mounted on a fixed, frictionless, horizontalaxle. When does the reel have a greater magnitudeof angular acceleration? (a) When the cord ispulled down with a constant force of 50 N. (b) Whenan object of weight 50 N is hung from the cord andreleased. (c) The angular accelerations in parts (a) and(b) are equal. (d) It is impossible to determine.
