* 22. An 830-kg race 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 m. Air flowing over the car's wing exerts a
downward-pointing force (called the downforce) of 11 000 N on the
car. (a) What is the coefficient of static friction between the track
and the car's tires? (b) What would be the maximum speed if no
downforce acted on the car?
