I need help (formula or tips) for solving friction force question

  1. Sep 26, 2006 #1
    the question is

    A 35kg crate rests on the back end of a flat bed truck. the coefficient of static friction between the crate and the bed is 0.175

    what is the maximum force of static friction that the truck's bed can exert on the crate?

    b) what is the maximum acceleration the static friction can cause the crate to have?

    plz help..
    thakn you :smile:

    What is the force on the crate when the truck's acceleration is a? (with the box not sliding) What supplies that force? (hint: it has something to do with friction). What is the maximum force of (static) friction between the truck and the box? Answer those questions and you will be able to solve this.
