At the instant of takeoff, a 53 kg diver's angular momentum (H) about her transverse axis is 15 kgm2/s. Her radius of gyration (rg) about the transverse axis is 1.1 m at this instant. During the dive, the diver tucks and reduces her radius of gyration about the transverse axis by 50%.
(A) At takeoff, what is the diver's angular velocity about the transverse axis?
(B) After the diver tucks, what is her angular velocity about the transverse axis?
Show ALL work. Explain the answer in words (if necessary).
