a student sits on a rotating stool holding two 8.0 kg objects. When his arms are extended horizontally, the objects are 1.3 m from the axis of rotation and he rotates with an angular speed of 1.9 rad/s. The moment of inertia of the student plus stool is 3.3 kg•m^2 and is assumed to be constant. If the student pulls in the two objects horizontally to 0.50 m from the rotation axis. What is the new angular speed (in rad/s) of the student?

Hi please help:
a student sits on a rotating stool holding two 8.0 kg objects. When his arms are extended horizontally, the objects are 1.3 m from the axis of rotation and he rotates with an angular speed of 1.9 rad/s. The moment of inertia of the student plus stool is 3.3 kg•m^2 and is assumed to be constant.
If the student pulls in the two objects horizontally to 0.50 m from the rotation axis. What is the new angular speed (in rad/s) of the student?
