Consider the following figure. A race track is constructed such that two curves of constant radius, 80 m at A and 40 m at B, are joined by two stretches of straight track as in the figure above. While testing a new car, a driver travels at a constant speed of 50 m/s for one complete lap. Which one of the following options is correct for the ratio of the centripetal acceleration of the car at A to the centripetal acceleration of the car at B?

Question
Consider the following figure.
While testing a new car, a driver travels at a constant speed of 50 m/s for one complete lap.
A race track is constructed such that two curves of constant radius, 80 m at A and 40 m at B, are joined by two stretches of straight track as in the figure above.
Which one of the following options is correct for the ratio of the centripetal acceleration of the car at A to the centripetal acceleration of the car at B?
acA/acB = 1/2
acA/acB = 1/4
acA/acB = 2
acA/acB = 4
The centripetal acceleration is zero at both points.
