A runner taking part in the 200-m dash must run around the end of a track that has a circular arc with a radius of curvature of 30 m. If he completes the 200­-m dash in 23.2 s and runs at constant speed throughout the race, what is the magnitude of his centripetal acceleration as he runs the curved portion of the track?

A runner sprints around a circular track of radius 100 m at a constant speed of 7 m/s. The runner's friend is standing at a distance 200 m on from the center of the track. How fast is the distance between the friends changing when the distance between them is 200m?

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. What is her centripetal acceleration during the turn at each end of the track?
