A flat (unbanked) curve on a highway has a radius of 250 m. A car successfully rounds the curve at a speed of 35 m/s but is on the verge of skidding out. a. Draw free body diagram of the car. b. If the coefficient of static friction between the car's tires and the road surface were reduced by a factor of 2, with what maximum speed could the car round the curve without slipping? c. Suppose the coefficient of friction were increased...
A highway curve of radius 68.0 m is banked at 21.4 degree so that a car traveling at 26.4 m/s (95 km/hr) will utilize both banking and friction to keep it on the curve. Determine the minimum coefficient of static friction between the tires and the road to keep the car on the road at this speed on this curve.

Two curves on a highway have the same radii. However, one is unbanked and the other is banked at an angle of degrees. A car can safely travel along the unbanked curve at a maximum speed under conditions when the coefficient of static friction between the tures and the road is . The banked curve is frictionless, and the car can negotiate it at the same maximum speed . Find the coefficient of static friction between the tires and the...
A car goes around a curve on a road that is banked at an angle of 33.5 degree. Even though the road is slick, the car will stay on the road without any friction between its tires and the road when its speed is 23.0 m/s. Part A What is the radius of the curve?
A car rounds a curve that is banked inward. The radius of curvature of the road is R = 140 m, the banking angle is θ = 26°, and the coefficient of static friction is μs = 0.39. Find the minimum speed that the car can have without slipping. A car rounds a curve that is banked inward. The radius of curvature of the road is R 140 m, the banking angle is 26e, and the coefficient of static minimum...
