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?

- A skater goes for a jump with turns. When she extends her arms, her moment of inertia about an axis through his body is 1.750 kg*m2. She initially pins at 0.650 rev/s and launches herself into the air and remained there for about 1.570 seconds while spinning at a constant angular speed.
