Here is the question:

Q. A highway curve that has a radius of curvature of 100m is banked at an angle of 15 degree.

a) Determine the vehicle speed for which this curve is appropriate if there is no friction between the road and the tires of the vehicle.


On a dry day when friction is present, an automobile successfully negotiates the curve at a speed of 25m per second.
b) Tell me all the forces on the automobile.
c) Determine the minimum value of the coefficient of friction necessary to keep this automobile from sliding as it goes around the curve.

I would appreciate your response to each question!
