An 815-kg race car can drive around an unbanked turn at a maximum speed of 61 m/swithout slipping. The turn has a radius of curvature of150 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of2500 N on the car.
a) What is the coefficient of static friction between the track and the car's tires?b) What would be the maximum speed if no downforce acted on thecar?
