v = d/t = 200/22.9 = 8.73 m/s
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.
Randomized Variables r = 35 m t = 22.9 s
If he completes the 200 m dash in 22.9 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?
