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

    A load of 200kg rests on a horizontal plane.A horizontal force of 196N is needed to overcome friction.Find the coefficient of friction

    2. Relevant equations
    F(friction)= (mu)N

    3. The attempt at a solution

    This then is the F(normal) also.


    thanks in advance
