Acrate of eggs is located in the middle of the flatbed 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 35.0 m. if the coefficient of static friction between crate and truck is 0.600, how fast can the truck be moving without the crate sliding?

v = 14.35 m/s

Explanation:

As we know that crate is placed on rough bed

so here when pickup will take a turn around a circle then in that case the friction force on the crate will provide the necessary centripetal force on the crate

So here we have

here we have

now we know that

here we have

R = 35 m

g = 9.81 m/s/s

now plug in all values in above equation

because if the tool that you are using is not balanced it there would be false mass.

snell's law

refractve index = sin incidence / sin refraction
