A trapese artist must make a quadruple somersault in t = 1.6 seconds. For the first and last quarter revolutions, he is in the extended orientation shown in the figure with I1 = 19.9 kg m2 around his center of mass. During the rest of the flight he is in a tight tuck, with rotational inertia I2= 3.92 kgm2. What must be his angular speed ω2 around his center of mass during the tuck?
