An engine flywheel initially rotates counterclockwise at 5.55 rotations per second. Then, during 24.5 seconds, its rotation rate changes to 2.89 rotations per second clockwise. Find the flywheel\'s average angular acceleration (including its sign) in rad/s2. Define counterclockwise rotation as positive.
