Three math instructors are trying to hold a sedated bear in the center of a class- room. There are three ropes attached to the bear and each instructor has hold of a rope. Mark is pulling in the direction 15° East of North with a force of 20 pounds and Allison is pulling in the direction 25° East of South with a force of 30 pounds. You must quickly tell Joe the compass direction and the magnitude of the force which must be exerted on the third rope to counterbalance Mark and Allison.
