58) Newton's Second Law in 2 Dimensions: A 1000-kg barge is being towed by means of two horizontal cables. One cable is pulling with a force of 80.0 N in a direction 30.0° west of north. In what direction should the second cable pull so that the barge will accelerate northward, if the force exerted by the cable is 120 N? Assume that the water exerts no appreciable frictional drag on the barge. A) 19.5° east of north B) 21.1° east of north C) 39.0° east of north D) 47.5° east of north E) 54.7° east of north
