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
