Some objects with different shapes, masses, and radii are rolling on a flat surface, and they all have the same velocity. Their shapes are a sphere, a tube , or a cylinder Order them by their total kinetic energy (rotational plus translational)., e. g. "1" is highest, "2" is second highest, etc. For ties put the same answer for both objects, and the next rank is increased by one, e. g. you can't have 11 2. 2A cylinder of mass 0.5 kg and radius 0.3 m 3 A tube of mass 1.0 kg and radius 0.2 m. A cylinder of mass 1.5 kg and radius 0.3 m The total KE is 1/2 mv2 + 1/2 cmv2. Note that the KE does not depend on the radius!
