[kierans]

Homework Statement

A horse is of the bank of a river pulling a barge in the same direction. Suppose the horse pulls on the rope with a force of 8600 N at an angle θ = 18Degrees to the direction of the motion of the barge, which is headed straight along the positive direction of an x-axis. The mass of the barge is 9500 kg, and the magnitude of its acceleration is 0.12 m/s2. What are the (a) magnitude and (b) direction (relative to positive x) of the force on the barge from the water?

You should show some work. At least draw a force diagram for yourself and post what you get for the sum of forces in the x and y directions.
