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?
express your answer using two significant figures.
