Bob and Lily are riding on a typical carousel. Bob rides on a horse near the outer edge of the circular platform, and Lily rides on a horse near the center of the circular platform. When the carousel is rotating at a constant angular speed, Bob's angular speed is A. exactly half as much as Lily's. B. the same as Lily's. C. larger than Lily's. D. exactly twice as much as Lily's. E. smaller than Lily's.

B.the same as Lily's.

Explanation:

When a disc is rotating on its axis uniformly with some angular velocity , every particle on it rotates with the same angular velocity , because every particle on it completes a rotation simultaneously . So in one rotation they take same time . Hence   particles whether on the outer edge or near the axis , all have same angular velocity .

They but differ due to their different linear velocity . Linear velocity of particle near outer edge have greater magnitude.  .
