The speed of a car increases uniformly with time from 50km/hr at A to 100km/hr at B during 10 seconds.
The radius of curvature of the bump at A is 40m.
if the magnitude of the total acceleration of the car's mass center is the same at B as at A, compute the radius of curvature of the dip in the road at B. The mass center of the car is 0.6m from the road.
