A sailboat weighing 1,007 lb with its occupants is running down wind at 8 mi/h when its spinnaker is raised to increase its speed. Determine the magnitude (eve value) of the net force in lb, provided by the spinnaker over the 12-s interval that it takes for the boat to reach a speed of 14 mi/h. Use Impulse-momentum. Round your answer to one decimal place. Use the proper conversion factors/units. Type your answer as a positive value
