Consider a banked wet curved 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 R= 50 m. If the banking angle is 8= 25 a) What is the maximum speed the automobile can have before sliding up the banking? b) What is the minimum speed the automobile can have before sliding down the banking?
