B. An ice skater is preparing for a twirling jump. Their arms are initially extended giving them a moment ofinertia I = 1.8 kg m2. They launch themselves into the air with v = 9.0 m/s @ 45 above the ice. a) How long will they be in the air? b) If they are spinning at 0.5 revfs before the jump, and their moment of inertia during the entire jump changes to I = 0.5 kg m2, at what rate are they spinning while in the air? c) Overall how many revolutions can they execute while airborne
