Lily is a 50 kg diver. At the instant of takeoff, her angular momentum about her longitudinal axis is 20 kgm2/s. Her radius of gyration about the longitudinal axis is 0.4 m at this instant. During the dive, Lily tucks and reduces her radius of gyration about the longitudinal axis to 0.2 m. a. At takeoff, what is Lily’s moment of inertia about her longitudinal axis? b. At takeoff, what is Lily’s angular velocity about her longitudinal axis? c. After Lily tucks, what is her moment of inertia about her longitudinal axis? d. After Lily tucks, what is her angular velocity about her longitudinal axis?
