Answer ( 1 )

  1. 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.
