The speed of a car increases uniformly with time from 64 km/h at A to 89 km/h at B during 9 seconds. The radius of curvature of the hump at A is 41 m. If the magnitude of the total acceleration of the mass center of the car is the same at B as at A, compute the radius of curvature pg of the dip in the road at B. The mass center of the car is 0.55 m from the road. Assume PA = 41 m, h = 0.55 m. Answer: PB = i B PB m
