please show the steps how its done
A student stands at the center of a turntable, holding her armsextended horizontally. She has 3.0 kg dumbbells in each hand. Sheis set rotating about a vertical axis, making one revolution in 1.0s. Her moment of inertia (without the dumbbells) is 3.0 kg m2 whenher arms are outstretched, and drops to 2.0 kg m2 when her arms arepulled in close to her body. The dumbbells are 1.0 m from the axisinitially and 0.20 m from it at the end. Find the students newangular velocity when she pulls the dumbbells close to her body
