Consider a wet roadway banked as in Example 5.24, where there is acoefficient of static friction of 0.30 and a coefficient of kineticfriction of 0.25 between the tires and the roadway. The radius ofthe curve is R=50m.
a) If the banking angle is β =25 degrees,what is the maximum speed the automobile can have before sliding upthe banking?
b) What is the minimum speed the automobile can have before sliding down the banking?
