When a diver gets into a tuck position by pulling in her arms and legs, she increases her angular speed. before she goes into the tuck position, her angular velocity is 5.5 rad/s, and she has a moment of inertia of 2.1 kg · m2. once she gets into the tuck position, her angular speed is 12.9 rad/s. determine her moment of inertia, in kg · m2, when she is in the tuck position. assume the net torque on her is zero.
Answers: 2
= Final angular velocity = 12.9 rad/s
= Initial angular velocity = 5.5 rad/s
= Initial moment of inertia = 2.1 kgm²
= Final moment of inertia
