A majorette in the Rose Bowl Parade tosses a baton into the air with an initial angular velocity of 2.5 rev/s. If the baton undergoes a constant acceleration while airborne of -0.2 rev/s 2 and its angular velocity is 0.8 rev/s when the majorette catches it, how many revolutions does it make in the air?
