3. The speed of a car increases uniformly with time from 100 km/h at A to 150 km/h at 8 during 20 seconds. The radius of curvature of the hump at 8 is 200 m. If the magnitude of the total acceleration of the mass center of the car is the same at 8 as at A, compute the radius of curvature of of the road at A. The mass center of the car is 0.6 m from the road. Show Transcribed Text 0.6 m 40 m Problem 3
