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?
