An engine flywheel initially rotates counterclockwise
at 6.61 rotations/s. Then,
during 20.5 s, its rotation rate changes
to 3.53 rotations/s clockwise. Find the flywheel's
average angular acceleration (including its sign) in radians per
second squared. Define counterclockwise rotation
as positive.
