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 14kg⋅m^2 and in a tucked position is 4.0 kg. m^2, by what factor is her angular velocity when tucked greater than when straight?
