Consider a wet banked roadway, where there is a coefficient of static friction of 0.30 and a coefficient of kinetic friction of 0.25 between the tires and the roadway. The radius of the curve is 50 meters.

If the banking angle is 25 degrees, what is the maximum speed the automobile can have before sliding up the banking?

What is the minimum speed the automobile can have before sliding down the banking?
