An object's angular velocity changes from 3 rad/s clockwise to 8 rad/s clockwise over 5 s. What is its angular acceleration?

A0.6 rad/s^2
B1 rad/s^2
C1.6 rad/s^2
D5 rad/s^2
Answer & Solution
Correct answer: B. 1 rad/s^2
1. alpha = delta omega / delta t = (8 - 3) rad/s / 5 s. 2. alpha = 5 / 5. 3. alpha = 1 rad/s^2. _Source: OpenStax Physics (CC BY 4.0), Ch 6 "Circular and Rotational Motion", section 6.3 Rotational Motion_
