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 39.6 m. If the coefficient of static friction between crate and truck is 0.630, how fast can the truck be moving without the crate sliding?

Answer 1

ma=F(fr),
mv²/R =μmg,
v=sqrt(μRg) = sqrt(0.63•39.6•9.8)= …
