Problem
Four identical-looking uniform disks—A, B, C, and D—are mounted on frictionless axles. Each disk is subjected to the same constant net torque for the same amount of time. The rotational inertias of the disks satisfy IA<IB<IC<ID. Which disk experiences the greatest angular acceleration during the interval?
(a) Disk D
(b) Disk A
(c) All four disks experience the same angular acceleration
(d) Cannot be determined from the information given
