A turn on a racetrack has a radius of curvature of 2000 ft and a bank angle theta. If cars travel at 140 mph through the turn find a) the minimum bank angle so the cars won't slip sideways during the turn. Neglect frictional forces b) Using the answer from pt a. find the maximum speed (mph) that the car can travel considering the coefficient of friction between the tires and the pavement to be 0.4
