Resolving Forces question applied force and friction force

  1. Nov 17, 2012 #1
    1. The problem statement, all variables and given/known data

    In earlier days, horses pulled barges down canals in the manner show in the figure below. Suppose that
    the horse pulls on the rope with a force of 7900N at an angle of 18 to the direction of motion of the
    barge, which is headed straight along the canal. The mass of the barge is 9500 kg, and its acceleration
    is 0.12m/s2. What are (a) the magnitude and (b) the direction of the force on the barge from the
    water?

    2. Relevant equations

    Kindly see if my orientation to solving the question is correct. If not ? Correct me.

    3. The attempt at a solution

    I resolve the force i.e 7900xsin(18)

    Then I use "Applied Force - Friction Force = Mass x Acceleration"

    7900xsin(18)= Applied Force
    Friction Force= I have to calculate
    Mass= It is given
    Acceleration= It is given in question ...

    The answer (Friction Force) is 1301.23N

    Is it correct ?

    There is no figure.
