AN 830 kilogram sports car can drive around an unbanked turn at a max. speed of 58 m/s without slipping. Urn has radius of curvature of 160 meter. Air flowing over the car's wing exerts a downward-pointing force (called down force) of 11,000 N on the sports car.
(a) Find coefficient of static friction between track and car's tires?
(b) Find the maximum speed if no down force acted on the car?
