Two identical wheels, wheel 1 and wheel 2, initially at rest begin to rotate with constant angular accelerations $ alpha$ . After rotating through the same angular displacement, $ Deltatheta_0$, the angular velocity of wheel 1 is $ omega_1$ and the angular velocity of wheel 2 is $ omega_2=3omega_1$ . How does the angular acceleration of wheel 2, $ alpha_2$, compare to the angular acceleration of wheel 1, $ propto

Two identical wheels, wheel 1 and wheel 2, initially at rest begin to rotate with constant angular accelerations

A
B
C
D

Explanation:

Detailed explanation-1: -A wheel which is initially at rest is subjected to a constant angular acceleration about its axis.

Detailed explanation-2: -We should also note that when the wheel is rotating at a constant speed, though all points on the wheel have the same angular speed, , their instantaneous linear speeds, in the direction tangent to the circles in which they are rotating, are proportional to their distance from the axis of rotation.
