Consider the following figure. 40 m 80 m 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? O acaca = 1/2 O alacB = 1/4 O acalac = 2 O aala cs = 4 O The centripetal acceleration is zero at both points.
