Kinetic Friction Question

  1. Sep 18, 2008 #1
    1. The problem statement, all variables and given/known data
    "A forward horizontal force of 50N is used to pull a crate, which weighs 250N, at a constant velocity across a horizontal floor. The coefficient of kinetic friction is:"

    2. Relevant equations
    Frictional force = coefficient of kinetic friction x normal force

    3. The attempt at a solution
    This problem seems too easy, that's why I'm wondering if I might be wrong:

    Frictional force = coefficient of kinetic friction x normal force
    50N = coefficient x 250N
    50N / 250N = coefficient
    coefficient = 0.2

    Is that all? Thanks
