**Part A**

Velocity:

$\overline{){\mathbf{v}}{\mathbf{=}}{\mathbf{r}}{\mathbf{\omega}}}$

r_{B} is greater than r_{A}. Thus, B has greater magnitude of velocity.

A merry-go-round is rotating at constant angular speed. Two children are riding the merry-go-round: Ana is riding at point A and Bobby is riding at point B.

Part A Which child moves with greater magnitude of velocity?

- Ana has the greater magnitude of velocity.
- Bobby has the greater magnitude of velocity.
- Both Ana and Bobby have the same magnitude of velocity.

Part B Who moves with greater magnitude of angular velocity?

- Ana has the greater magnitude of angular velocity.
- Bobby has the greater magnitude of angular velocity.
- Both Ana and Bobby have the same magnitude of angular velocity.
