Answer #1

(a) Centripetal acceleration is

(b) When the vehicle completes one revolution, it comes back to the initial point from where it started its motion. Therefore, displacement of the vehicle is zero.

Average Velocity is given by

Since, total displacement is zero when vehicle completes a revolution.

Hence, average velocity of the vehicle during one complete revolution is zero.
