8. Centripetal Forces & Gravitation
Banked Curves
2PRACTICE PROBLEM
The banked, circular highway curves are specifically designed for high-speed driving. To prevent vehicles from slipping outward, an 85 m radius highway curve is banked at a 28° inclination. Determine the maximum speed with which a high-speed car weighing 1800 kg can safely maneuver this curve without sliding off the road. The coefficient of friction between the tire and the road is 1.
