A car travels three quarters of the way around a circle of radius 20.0 m in a time of 3.0 s at a constant speed. The initial velocity is west and the final velocity is south.
a) Find its average velocity for this trip.b) What is the car's average acceleration during this 3.0 s?c) Explain how a car moving at constant speed has a non-zero average acceleration.
