A 1500kg car travels at a constant speed of 22 m/s around a circular track that has a radius of 85 m.
What is the average velocity of the car during one revolution?

    Zero. Do you see why? After one revolution, you are back where you started.

    Zero is also the time average of the velocity vector, since it spends equal times pointing in all directions.
