CHAPTER 9 ROTATIONAL DYNAMICS
... 15. REASONING AND SOLUTION The translational kinetic energy of a rigid body depends only on the mass and the speed of the body. It does not depend on how the mass is distributed. Therefore, for purposes of computing the body's translational kinetic energy, the mass of a rigid body can be considered ...
