A NASCAR racecar rounds one end of the Martinsville Speedway. This end of the track is a turn with radius approximately 57.0 m. If we approximate the track to be completely flat and the racecar is traveling at a constant 24.5 m / s (about 55 mph) around the turn, what is the racecar\'s centripetal (radial) acceleration?
What is the force responsible for the centripetal acceleration in this case?
