# Astudent sits on a rotating stool holding two 2.8-kg objects. when his arms are extended horizontally, the objects are 1.0 m from the axis of rotation and he rotates with an angular speed of 0.75 rad/s. the moment of inertia of the student plus stool is 3.0 kg · m2 and is assumed to be constant. the student then pulls in the objects horizontally to 0.34 m from the rotation axis. (a) find the new angular speed of the student.
