A 940-kg race car can drive around an unbanked turn at a maximum speed of 43 m/s without slipping. The turn has a radius of 180 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 13000 N on the car. (a) What is the coefficient of static friction between the track and the car's tires

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving
