Force of Friction

  1. Jun 7, 2016 #1
    1. The problem statement, all variables and given/known data
    Mass: .034kg
    Acceleration: -.3644
    Time:2.744sec
    Inital Velocity: 1m/s
    The path is on a flat surface

    2. Relevant equations
    Ff=mu(Fn)
    F=m*a

    3. The attempt at a solution
    I need help find the coefficient of friction. I'm trying to find the difference of mu between oil, water, and a dry surface, and I lack Ff, or I do not know how to find it without mu. Is there anyway to find the solution. Thank you

    Unless you were given varying information for each case, you'd need to look those μ values up in a table

    You know the mass and the acceleration.
    What/who's law relates Force, mass and acceleration?
