In this article (and video above), we take a deep dive into the world of rotational kinematics, and explore the significance of using the 4 constant angular acceleration equations to solve complex problems and unravel the mysteries of rotating objects.
Question:
The disk presented in the figure accelerates uniformly from rest at a rate of 2 rad/s^2 for 4 seconds. It then maintains a constant angular velocity for 4 seconds before decelerating uniformly at a rate of 5 rad/s^2 until it comes to rest.
What is the total angular displacement of the disk?
