Uniform Circular Motion Question!

  1. Nov 20, 2008 #1
    On a circular racetrack, a car travels 2.0km at a speed of 120 km/h in completing one lap.

    A) What is the change in velocity in one quarter of a revolution?
    B) What is the change in velocity in half a revolution?

    Thanks for the help.
