2/107 The speed of a car increases uniformly with time from 50 km/h at A to 100 km/h at B during 10 sec onds. The radius of curvature of the hump at A is 40 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 0.6 m from the road. 40 m A 0.6 m Problem 2/107 B PB
