An icer-skater is preparing for a jump in which she will rotate while in the air. While on the ground with arms extended her moment of Inertial_initial- 2.4 kg*m2 and she is spinning at 0.5 rev/s. She launches into the air at speed of 15 m/s at 0-40%. As soon as she leaves the ground she contracts her arms instantaneously reducing her body's inertia to.8 kg*m? How many revolutions can she complete before touching the ground? Range=R-Vo?* sin(2°C)/g where g=9.8 m/s/s the projection angle in radians [Choose angular velocity in revolutions/sec after take off when she contracts her hands [Choose horizontal velocity Vox at take-off m/s [Choose vertical velocity Voy at take-off m/s [Choose time to reach apex in s Choose height of apex in m Choose total range [Choose time to reach range [Choose total revolutions [Choose
