Thrown for a Curve

To throw a curve ball, a pitcher gives the ball an initial angular speed of 157.0 rad/s.  When the catcher gloves the ball 0.795 s later, its angular speed has decreased (due to air resistance) to 154.7 rad/s.

(a)  What is the ball’s angular acceleration, assuming it to be constant?

(b)  How many revolutions does the ball make before being caught?
