One cable is pulling with a force of 90.0 N in a direction 25.0° west of north. Assume that the water exerts no appreciable frictional drag on the barge. Determine the following, showing all your steps clearly: a. In what direction should the second cable pull so that the barge will accelerate northward, if the force exerted by the cable is 130 N? Give your answer as an angle relative to north and state which direction (east of north or west of north). b. What is the acceleration that the barge moves north with? c. How far does it move in the first 15 seconds?
