Question: A typical running track is an oval with 74-m-diameter half circles at each end. A runner going once around the track covers a distance of 400m. Suppose a runner, moving at a constant speed, goes once around the track in 1 min 40 s.

Part A: What is her centripetal acceleration during the turn at each end of the track?

I need help to find her centripetal acceleration during the turn at each end of the track.
