vector worksheet #4

Chapter 2 test Wednesday
chapter 2 review

• read page numbers 7 and 8 (review, read carefully)
• on page numbers 9-11 do problems 3-13, 15-18, 20, 22-29
• on page number 12 do problems 1, 2

vector worksheet #3

• problem 1, the bag of marbles weighs 101N (1 N per marble)
• problem 5 has an error. Treat the 15m/s similar to problem 2, meaning it is the vertical vector, the vector which in problem 2 represented the weight. The vectors you would solve for are the vector down the ramp and the vector into the ramp (same as problem 2).
