If average velocity is zero, then is average acceleration zero?
Can you give me an example?
Sure. Let's say a car is moving in a straight line at a constant speed of 50 km/hr. The car then suddenly brakes and comes to a stop. During the time it takes for the car to stop, the car's average velocity is 25 km/hr (since it started at 50 km/hr and ended at 0 km/hr), but its average acceleration is not zero because it had to decelerate to come to a stop.
