This question is all qualitative, but I don't know what centripetal and average acceleration is around a circle. The question is about two runners on a circular track, Runner A on the inside lane, Runner B on the outside lane. The runners have the same SPEED, I think that runner A has a larger centripetal and average acceleration because A has to make a sharper turn. But I think that A and B undergo the same change in velocity as the go around the whole track, even though A will reach the end first. Are my assumptions correct? Thanks
