Question

Question (part 1 of 2) A student sits on a rotating stool holding two 1 kg objects. When his arms are extended horizontally, the objects are 1.1 m from the axis of rotation, and he rotates with angular speed of 0.64 rad/sec. The moment of iner- tia of the student plus the stool is 4 kg m and is assumed to be constant. The student then pulls the objects horizontally to a radius 0.33 m from the rotation axis. KiSo 立立 Caleulate the final angular speed of the student. Answer in units of rad/s
Question (part 2 of 2) Calculate the change in kinetic energy of the system. Answer in units of J.
