A baton twirler tosses a baton into the air with an initial angular velocity of 2 rev/s (revolutions per second). The baton undergoes a constant angular acceleration of -.015 rev/s^2 while in the air, and its angular velocity when she catches it is .8 rev/s. Determine the number of revolutions the baton made while in the air
