Rotation with Constant Angular Acceleration
The equations for constant angular acceleration are obtained in identical fashion to the translational constant acceleration equations. They are listed in the Master Table.
Example A flywheel is spinning at 100 revolutions per second
and is stopped by a brake in 10 seconds. What is the angular acceleration of the flywheel ?
Solution The initial angular velocity is
and the final angular velocity is 
. Using 
gives
