Aroad race is taking place along the track shown in the figure (figure 1). all of the cars are moving at constant speeds. the car at point f is traveling along a straight section of the track, whereas all the other cars are moving along curved segments of the track.

assuming that all cars have equal speeds, which car has the acceleration of the greatest magnitude, and which one has the acceleration of the least magnitude?

give your answer as "x, y" where x is the car with the greatest magnitude of acceleration and y is the car with the least magnitude of acceleration.

hint 1. how to approach the problem opened hint recall that the magnitude of the acceleration of an object that moves at constant speed along a curved path is inversely proportional to the radius of curvature of the path.
