A figure skater is trying to work on her axel jump and spins routine before the competition starts. Her moment of inertia is 1.8 kg x m^2 while her arms are extended, and is spinning at 0.5 rev/s. If she launches herself into the air at 9.0 m/s at an angle of 45 degrees with respect to the ice, how many revolutions can she execute while airborne if her moment of inertia in the air is 0.5 kg x m^2?
