In earlier days, horses pulled barges down canals in the manner shown in the figure. Suppose the horse pulls on the rope with a force of 7920 N at an angle of 0= 15.0° 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 9510 kg, and the magnitude of its acceleration is 0.120 m/s. What is the magnitude of the force on the barge from the water? (Note to Student: Don't include the forces perpendicular to the surface of the water in the solution to this problem, namely the gravitational and buoyant forces.)

Question
In earlier days, horses pulled barges down canals in the manner shown in the figure. Suppose the horse pulls on the rope with a force of 7920 N at an angle of 8 = 15.0° 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 9510 kg, and the magnitude of its acceleration is 0.120 m/s. What is the magnitude of the force on the barge from the water? (Note to Student: Don't include the forces perpendicular to the surface of the water in the solution to this problem, namely the gravitational and buoyant forces.) Step 1 Create the free-body diagram. Put water force at 240°. Use the checkboxes to select the correct vectors as instructed above. Move the vectors to the correct starting points and orient them in the correct direction as instructed. Fw f FN T Draw free-body diagram here Key to Force Labels Fw Water force f Frictional force FN Normal force T = Tension Point the acceleration vector in the correct direction
