    A barge is hauled along a straight-line section of canal by two horses harnessed to tow ropes and walking along the tow paths on either side of the canal. Each horse pulls with a force of[COLOR=red]610[/COLOR] N at an angle of [COLOR=red]16[/COLOR]° with the centerline of the canal. What is the net force on the barge?

    Sounds like homework. You copied the assignment, but you forgot to copy your answer and your work you used to find it, right or wrong... therefore there is notihng we can do because we don't do the assignment for you.

    You need to reso;ve each of the tow rope forces intop components parallel to the direction of travel (let;s call that the x-direction) and perpendicular to the direction of travel (y directin), using sines and cosines of 16 degrees. Hint: be careful with the signs of your results. Then add the x-componenets to get the total force in the x-direction, and the y-components to get the total foprce in the y-direction. Try itl and post back with your answer.
