1. The problem statement, all variables and given/known data A student sits on a rotating stool holding two 4.0 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 the objects horizontally to 0.50 m from the rotation axis. (a) Find the new angular speed of the student. rad/s (b) Find the kinetic energy of the student system before and after the objects are pulled in. 2. Relevant equations 3. The attempt at a solution Tried working the problem but got stuck with not having the moment of inertia after the weights are pulled in. All of the examples my proffessor worked in class gave us both so i am unsure how to solve for it.
