At the instant shown, the centers of the two identical uniform disks A and B are moving to the right with the same speed υ0. In addition, disk A is rolling clockwise with an angular speed ω0 while disk B has a backspin with angular speed equal to ω0. Letting TA and TB be the kinetic energies of A and B, respectively, state which of the following statements is true and why: (a) TA < TB; (b) TA = TB; (c) TA > TB.

Note:Concept problems are about explanations, not computations.
