A disk rotates about an axis through its center. Point A is located on its rim and point B is located exactly one third of the way from the center toward the rim. What is the ratio of the angular velocity A to that of B, and the tangential velocity vA to that of vB?
(a)
the angular velocity A to that of B
| A |
| B |
=
(b)
the tangential velocity vA to that of vB
| vA |
| vB |
=
