APFIVE Torque and Angular Acceleration
A uniform disk and a uniform hoop, both with the same mass and radius, are initially at rest at the top of an incline. If a constant torque is applied to both objects, how does the angular acceleration of the disk compare to that of the hoop?
A
The disk’s angular acceleration is 4 times greater
B
The hoop’s angular acceleration is 2 times greater
C
The disk’s angular acceleration is 2 times greater
D
Both have the same angular acceleration
