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 50 m. The runner starts the race at a constant speed. If she completes the 200 m dash in 23.4 s and runs at constant speed throughout the race, what is the magnitude of her centripetal acceleration (in m/s2) as she runs the curved portion of the track
Answers: 1
) is equal to the square of the velocity, divided by the radius of the circular path.
