Define counterclockwise rotation as positive

Reference no: EM13547092

An engine flywheel initially rotates counterclockwise at 5.39 rotations per second. Then, during 21.3 seconds, its rotation rate changes to 2.11 rotations per second clockwise. Find the flywheel\'s average angular acceleration (including its sign) in rad/s2. Define counterclockwise rotation as positive.
