Two uniform rods of identical mass and identical length are rotating with identical rotational kinetic energy. The first rod is rotating about and axis that passes through its left end and points perpendicular to the rod. The second rod is rotating about an axis that passes through its center and points perpendicular to the rod. Which rod has a larger magnitude of angular velocity?
a. They both have the same magnitude of angular velocity.
b. The second rod.
c. The first rod.
