An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of $0\mathrm{.}200re\frac{v}{s}.$ The magnitude of the angular acceleration is $0\mathrm{.}896re\frac{v}{s^2}.$ Both the the angular velocity and angular accleration are directed counterclockwise. The electric ceiling fan blades form a circle of diameter $0\mathrm{.}720$ m $.$

Compute the fan's angular velocity magnitude after time $0\mathrm{.}191$ s has passed.

Express your answer numerically in revolutions per second.
