Divers change their body position in midair while rotating about their center of mass. In one dive, the diver leaves the board with her body nearly straight, then tucks into a somersault position. If the moment of inertia of the diver in a straight position is 14 kg m2 and in a tucked position is 4.0 kg m2, by what factor is her angular velocity when tucked greater than when straight?

Divers change their body position in midair while rotating about their center of mass. In one dive, the diver leaves the board with her body nearly straight, then tucks into a somersault position. If the moment of inertia of the diver in a straight position is 14 kg m2 and in a tucked position is 4.0 kg m2, by what factor is her angular velocity when tucked greater than when straight?
