Physics 7B Exit Handout DLM 08 FNTs: ( We won’t be covering these in detail so come with questions ). 6.1-1) Three force vectors are added together. One has a magnitude of 9 N, the second one a magnitude of 18 N, and the third a magnitude of 15 N. What can we conclude about the magnitude of the net force vector? Explain. I. It must equal 42 N. II. It cannot be 0 N. III. Anything from –42 N to +42 N. IV. It can be anything from 0 N to 42 N. V. None of the above can be concluded. 6.1-2) Alice, Bob and Chuck are three friends standing around talking. We know that Alice is standing 9 m away from Bob, and that Bob is standing 3 m away from Chuck. Let ∆R AB be the vector that starts at Alice and ends at Bob, and ∆R BC be the vector that starts at Bob and ends at Chuck. (a) Write an equation to find the displacement between Alice and Chuck. (b) What is the furthest Chuck can be from Alice, given the information in the question? What is the closest they can be?
