Linear and Rotational Quantities Conceptual Question

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

A) Which child moves with greater magnitude of velocity?

=> Isamu has the greater magnitude of velocity.

B) Who moves with greater magnitude of angular velocity?

=> Both Alan and Isamu have the same magnitude of angular velocity.

C) Who moves with greater magnitude of tangential acceleration?

=> Both Alan and Isamu have the same magnitude of tangential acceleration.

D) Who has the greater magnitude of centripetal acceleration?

=> Isamu has the greater magnitude of centripetal acceleration.

E) Who moves with greater magnitude of angular acceleration?

=> Both Alan and Isamu have the same magnitude of angular acceleration.
