Part A Which two vectors, when added, will have the largest x component? Hint A.1 Largest x component The two vectors with the largest x components will, when combined, give the resultant with the largest x component. Keep in mind that positive x components are larger than negative x components. ANSWER: C and E E and F A and F C and D B and D Part B Which two vectors, when added, will have the largest y component? Hint B.1 Largest y component Hint not displayed ANSWER: C and D A and F [ Print ]

Hint C.1 Subtracting vectors Hint not displayed ANSWER: A and F A and E D and B C and D E and F Vector Magnitude and Direction Conceptual Question A man out walking his dog makes one complete pass around a perfectly square city block. He starts at point A and walks clockwise around the block. Let be the displacement vector from A to B, be the displacement vector from B to C, etc. Part A Which of the following vectors is equal to ? Hint A.1 Determining a vector Hint not displayed Hint A.2 Equal vectors Hint not displayed

Part B Which of the following vectors is equal to ? ANSWER: only only only None of the above All of the above Part C Which of the following vectors is equal to ? Hint C.1 Determining the difference of two vectors Hint not displayed ANSWER: only only only None of the above All of the above Problem 3.19 Let 8.00 4.00 , 2.00 9.00 , and 3.00 . Part A Write vector as components, separated by a comma. For example, if you thought the x component was 3 and the y component was 4, then you would enter 3,4 .

Vectors may be manipulated either geometrically or using components. In this problem we consider the addition of
