Suppose that the horse pulls on the rope with a force of 7900 N 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 9800 kg, and its acceleration is 0.10 m/s2. What are the magnitude and the direction of the force on the barge from the water?

so what about current direction and wind drift? what is the surface aera below the waterline of the barge, is it salt or fresh water [this will affect the below waterline surface area] does this really matter?

The rudder of the barge must generate a force of (-) 7900(sin18) for the barge to stay in the middle of the canal
