The student sits on a pivoted stool while holding a weight ineach outstretched hand. The stool rotates about a verticalaxis through its center. The moment of intertia of thestudent, weights, and stool is 2.2.5 kg-m2 , and theinitial angular speed is 5.0 rads/s. As the student rotateson the stool, the weights are pulled inward so that the new momentof inertia becomes 1.80 kg-m2. Calculate the new angular speed of the system.
