During a jump to his partner, an aerialist is to make a quadruple somersault lasting a time t =1.51 s. For the first and last quarter-
revolution, he is in the extended orientation shown in the figure, with rotational inertia /, = 20.6 kg-m around his center of mass (the dot).
During the rest of the flight he is in a tight tuck, with rotational inertia l = 3.94 kg-m. What must be his angular speed w, around his
