Compute all parts of given problem:
Problem: An 870-kg race car can drive around an unbanked turn at a maximum speed of 45 m/s without slipping. The turn has a radius of 170 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 9100 N on the car.
Part A: What is the coefficient of static friction between the track and the car's tires?
Part B: What would be the maximum speed if no downforce acted on the car?
I need help to find the coefficient of static friction between the track and the car's tires.
