An 805 kilogram race car can drive around an unbanked turn at a maximum speed of 56 m/s without slipping. The turn has a radius of curvature of155 meter. Air flowing over the car's wing exerts a downward-pointing force (called the down force) of 11500 Newton on the car.
(a) Estimate the coefficient of static friction between the track and the car's tires?
(b) Estimate the maximum speed if no down force acted on car?
