A crate rests on a flatbed truck which is initially traveling at 17.8 m/s on a level road. The driver applies the brakes and the truck is brought to a halt in a distance of 33.1 m. If the deceleration of the truck is constant, what is the minimum coefficient of friction between the crate and the truck that is required to keep the crate from sliding?

  1. vf^2=vi^2+2ad

    solve for a.
    Then
    forcefriction=masscrate*a you know a
    mu*masscrate*g=masscrate*a
    mu=a/g
