An 830 kilogram sports car can drive around an unbanked turn at a maximum speed of 58 m/s without slipping. The turn has a radius of curvature of 160 meter. Air flowing over the car's wing exerts a downward pointing force (called the down force) of 11000 N on the car
(a) Find coefficient of static friction between track and car tires?
(b) Calculate what would be the maximum speed if no down force acted on the car?
