A crate is resting on the bed of a moving truck. the coefficient of static friction between the crate and the truck bed is 0.40. the driver hits the brakes. assuming the truck is traveling on level ground, determine the maximum deceleration that the truck can have without the crate slipping forward relative to the truck.

can anyone please give me some hints to do it?THANKS A LOT!

  1. f=ma

    f is the force of friction, mu*masscrate*g

    m is the masscrate

    solve for a.
