Chapter 11, Problem 62P

GO During a jump to his partner, an aerialist is to make a quadruple somersault lasting a time t = 1.87 s. For the first and last quarter-revolution, he is in the extended orientation shown in Fig. 11-55, with rotational inertia I₁ = 19.9 kg·m² around his center of mass (the dot). During the rest of the flight he is in a light tuck, with rotational inertia I₂ = 3.93 kg·m². What must be his angular speed ω₂ around his center of mass during the tuck?
