Resolving Forces question applied force and friction force

[engboysclub]

Homework Statement

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?

Homework Equations

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

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 ?
