Aphysics professor that doesn’t get easily embarrassed stands at the center of a frictionless turntable with arms outstretched and a 5.0-kg dumbbell in each hand. he is set rotating about the vertical axis, making one revolution in 2.0s. find his angular velocity if he pulls the dumbbells to his stomach. his moment of inertia (without the dumbbells) is 3.0 kg*m^2 with arms outstretched and 2.2 kg*m^2 with his hands at his stomach. the dumbbells are 1.0 m from the axis initially and 0.20 m at the end. how about kinetic energy before and after? explain from where this energy (if any) came from?
