How fast can a racecar travel through a circular tum without skidding and hitting the wall? The answer could depend on several factors:
- The weight of the car;
- The friction between the tires and the road;
- The radius of the circle;
- The “steepness” of the turn.
In this project we investigate this question for NASCAR racecars at the Bristol Motor Speedway in Tennessee. Before considering this track in particular, we use
A car of mass m moves with constant angular speed to around a circular curve of radius R (Figure 3.20). The curve is banked at an angle
