A crate of eggs is located in the middle of the flat bed of a pickup truck as the truck negotiates a curve in the flat road. The curve may be regarded as an arc of a circle of radius 36.8m. If the coefficient of static friction between crate and truck is 0.590, how fast can the truck be moving without the crate sliding?
