A 850-kg race car can drive around an unbanked turn at a maximum speed of 61 m/s without slipping. The turn has a radius of 160 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 11000 N on the car. (a) What is the coefficient of ...

**science**

When you are describing the rate that a race car goes around a track, should you use the term speed or velocity to describe the motion? Can the velocity of the car change without changing the average speed of the car?
