A car moves at a constant speed of 90 km/h along a closed horizontal road in the shape of an ellipse with axes of 500 m and 250 m. On which sections of the road is the acceleration of the car maximum and minimum? What are the maximum and minimum accelerations? What should be the coefficient of friction between the road surface and the tires of the car so that the car does not skid when driving along an ellipse?
