Homework Statement
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 9200 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?
(a) Magnitude
(b) Direction (counterclockwise from the +x axis is positive)
Homework Equations

The Attempt at a Solution
I trigged it;
(mass of the barge x the acceleration)-force of the horse cos (angle) = nope
