You've been "Vectored!"
We finished up fill-in-the-blank notes over vectors today so that you all could work on HW #9 in class. I will attach my work below so that you can check yours.
I also passed out a review worksheet for section 6.3 so that you could get a feel for the quiz over basics of vectors.
Did you feel like the homework had problems that the notes did not cover?
Vector operations: 3u - 2v means multiply the components of vector u by 3 and the components of vector v by 2. Then subtract the resulting 2v from 3u. There are examples in the book; it's easy.
Two of the word problems from the book are about 2 forces. This was not in our notes. Try #79 first, as the picture helps, and the problem has a suggestion. You will still finish the what we did on the last problem of the notes.
#93 is a lot like the example we did in class.
#75 is not like anything we did. See my work attached.
Everyone should have gotten to see their test score. I will post before I leave today (Friday).
HW #9 - pp 425-7: 1-8, 15, 18, 19, 31, 34, 37, 51, 52, 64, 67, 70, 72, 75, 79, 93.
