Solve the all parts of given problem:

Problem: A student sits on a rotating stool holding two 2.2-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 0.28 m from the rotation axis.

Part I: Find the new angular speed of the student.

rad/s

Part II: Find the kinetic energy of the student before and after the objects are pulled in. before Incorrect: Your answer is incorrect. Your response differs from the correct answer by more than 10%. Double check your calculations. J after Incorrect: Your answer is incorrect. Your response differs from the correct answer by more than 100%.

J

I need the detailed solution of each step and calculation.
