A curve of radius 68 m is banked for a design speed of 85 km/h . Part A If the coefficient of static friction is 0.31 (wet pavement), at what range of speeds can a car safely make the curve? [Hint: Consider the direction of the friction force when the car goes too slow or too fast.] Express your answers using two significant figures separated by a comma.

Consider the motion of a car around a banked curve. The angle of the bank with respect to the horizontal is 15.0 degrees, the speed of the car is 20.0 m/s, the radius of curvature for the curve is 30.0 m, and the coefficient of static friction is 0.500. The mass of the car is 1000 kg. a) What is the frictional force? b) Is there a speed at which the frictional force would be zero? If so, what is...

A banked circular highway curve is designed for traffic moving at 62 km/h. The radius of the curve is 214 m. Traffic is moving along the highway at 41 km/h on a rainy day. What is the minimum coefficient of friction between tires and road that will allow cars to take the turn without sliding off the road? (Assume the cars do not have negative lift.)

A car moving with a constant speed of 85 km/h enters a circular, flat curve with a radius of curvature of 0.40 km. If the friction between the road and the car’s tires can support a centripetal acceleration of 1.25 m/s2, without slipping, does the car navigate the curve safely, or does it fly off the road?
