A truck with mass m = 1000 kg is traveling around a circular curve of radius r = 770 m when it begins to rain. The coefficients of static friction between the road and tires is μd = 0.62 when dry and μw = 0.27 when wet. Write an expression for the maximum magnitude of the force of static friction Ff acting on the truck if μs is the coefficient of friction. What is the maximum tangential speed that the truck can take the corner at without slipping when dry in m/s? What is the maximum tangential speed when wet in m/s?
