In earlier days, horses pulled barges down canals in the manner shown in Fig. 5-47. Suppose the horse pulls on the rope with a force of 8000 N at an angle of θ = 25° to the direction of motion of the barge, which is headed straight along the positive direction of an

*x* axis. The mass of the barge is 9600 kg, and the magnitude of its acceleration is 0.15 m/s2. What are (a) the magnitude and (b) the direction of the force on the barge from the water? (Measure the direction

*clockwise* from the direction of motion, and give your angle to the nearest degree.)
