    1. The problem statement, all variables and given/known data

    a flatbed truck is carrying a 20KG crate down a sloping road inclined 15 degrees above the horizontal. The coefficient of static friction between the crate and the bed in 0.400. what is the maximum acceleration that a truck can have if th4 crate is to stay in place?

    2. Relevant equations



    3. The attempt at a solution

    What is the acceleration of the crate with respect to the ground?
    If there is acceleration, there is a net force of F=ma. What forces act on the crate?
