A racetrack curve has radius 80.0 m and is banked Part A at an angle of 21.0°. The coefficient of static friction between the tires and the roadway is 0.400. A race car with mass 1200 kg rounds the curve with the maximum speed to avoid skidding. As the car rounds the curve, what is the normal force exerted on it by the road? Express your answer with the appropriate units. µA ? n = Value Units Submit Request Answer Part B What is the car's radial acceleration? Express your answer with the appropriate units. HA Arad = Value Units Submit Request Answer Part C What is the car's speed? Express your answer with the appropriate units.
