A person sitting on a rotating stool has two weights in his hands, each with a 10Kg dough. When opening its arms, as shown in the figure, the weights are 0.9 m from the axis of rotation and the rotates with an angular velocity of 3 rad/s. The moment of inertia of the person plus the stool is 5 Kg m2 and is constant. If the person moves the weights 0.25m from the axis of rotation. The angular speed of the system is:
