need assistance with solving letter C

Expert Solution

Step 1

Given data:
The angular velocity is: $ω = - 3 rad/s$
The angular acceleration is: $α = + 2 {rad/s}^{2}$

To find:
The correct pictorial depiction of the motion.

In angular mechanics, a rotation in the counterclockwise direction is considered to be a positive rotation. A rotation in the clockwise direction is considered to be a negative rotation.
