Question

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 35 m.

r = 35 m
t = 23.3 s

If he completes the 200 m dash in 23.3 s and runs at constant speed throughout the race, what is his centripetal acceleration as he runs the curved portion of the track in m/s2?
