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 400 m. suppose a runner, moving at a constant speed, goes once around the track in 1 min 40 s. what is her centripetal acceleration during the turn at each end of the track?
