In a grand prix race of mass m= 600 kg as it travels on a fast track on a circular arc of radius r =100 m because of the shape of the car and the wings on it. The passing air exerts a negative lift FL downward on the car. If the coefficient of static friction between the tire and the track is 0.75 and if the car is on the verge of sliding out of the turn when its speed is 28.6 m/s, what is the magnitude of the negative lift acting downward on the car
