A student is sitting on a swivel seat and is holding a (1.20x10^0) kg weight in each hand, rotating at (9.8200x10^0) rad/s when the weights are held in outstretched arms 0.75 m from the axis of rotation. How fast is the student rotating in units of rad/s when pulling the weights in to the axis of rotation? Express you answer with three significant figures. (The student's body can be approximated as a cylinder with mass of 65 kg and radius of 0.25 m). Initial Note: Your answer is assumed to be reduced to the highest power possible.
