  1. Oct 19, 2009 #1
    1. The problem statement, all variables and given/known data
    if the coefficient of the friction between a crate and the floor is .25 and a 160 nt crate must be moved, the horizontal force need to slide the crate is?


    2. Relevant equations

    f=ma
    u=f/n

    3. The attempt at a solution

    no idea how to begin

    You'll need to show some idea of what's going on before you can receive help.

    How does the given information fit into the equations you gave? Have you drawn a free body diagram of the forces on the crate?
