For all three situations, find the magnitude and direction of the tension force(s) exerted on Rochelle. If not enough information is given, say so. Explain your answers. a. Rochelle and Buddy pull on opposite ends of rope. The tension force exerted on Buddy is 15 N and is directed toward Rochelle. b. Now, one end of the rope is tied to a sturdy pole and Rochelle pulls on the other end. The tension force on the pole is 15 N directed toward Rochelle. c. Finally, Rochelle holds one rope in her left hand, and the other end of that rope is pulled by Joe. She holds another rope in her right hand, and the other end of that rope is pulled by Buddy. Both Buddy and Joe experience a 15-N force directed toward Rochelle.

In this chapter, you've encountered a large number of concepts it related to forces and motion. Organizing a concept map might help clarify the meanings of many of these concepts for you. As a stall, you examine Concept Map 2.2 pertaining to the concept of "net force" created by a student who had previously taken an introductory physics course. Unfortunately, this student had some misconceptions about this topic, so there are some blatant errors in the concept map. Locate and correct as many of these errors as you can. (hint: Carefully inspect the linking words used to connect the concepts and consider the meanings of the "propositions" they make.)
