Finding Minimum Force

  1. Sep 21, 2009 #1
    1. The problem statement, all variables and given/known data
    A sled is pulled over a horizontal surface where the kinetic coefficient of friction is .20. What is the minimum force necessary to keep the sled moving if its mass is 2 slugs?


    2. Relevant equations
    fs = Ns(mg)


    3. The attempt at a solution
    fs = (.20) (2 slugs) (32)
    =12.8

    This problem has got me stumped. Please help! Thank You.

    What is the unit of fs?

    I assume 12.8 N

    Unit force is N if mass is in kg.
