2. A barge floating in a canal is moving at a constant speed. The barge is being pulled by two horses moving on opposite sides of a canal. The rope connecting each horse to the barge makes an angle of 32.0 with the line of motion of the barge. There is a retarding drag force on the barge whose magnitude (in Newtons) is given by F=-220v, where v is the speed of the barge (in m/s). If the tension in each rope is 74.0 N, what is the speed of the barge?
