Consider a wet roadway banked as in Example 5.24, where thereis a coefficient of static friction of 0.30 and a coefficient ofkinetic friction of 0.25 between the tires and the roadway. Theradius of the curve is R=50m.
a) If the banking angle is β =25degrees, what is the maximum speed the automobile can havebefore sliding up the banking?
b) What is the minimum speed the automobile can have before slidingdown the banking?
