Give the negative of the following vectors: A = 2.0 m, north and B = 4.0 m, 30° south of west. N N Answer: W Practice Exercise 2.10 A -E W- 30° B -B 30° -E From the diagrams, -A = 2.0 m, south and -B = 4.0 m, 30° north of east. Note that we do not place a negative sign before the magnitude of the vectors. The negative sign (-) only indicates opposite direction and does not affect the magnitude. Give the negative of the following vectors: A = 6.0 units, southeast and B = 7.5 units, 67° north of west.

A fly enters through an open window and zooms around the room. In a Cartesian coordinate system with three axes along three edges of the room, the fly changes its position from point b(4.0m,1.5m,2.5m) to point e(1.0m,4.5in,0.5m) . Find the scalar components of the fly’s displacement vector and express its displacement vector in vector component form. What is its magnitude?
Check Your Understanding For the vectors given in Figure 2.13, find the scalar products AB and FC . The three displacement vectors A , B , and C in Figure 2.13 are specified by their magnitudes A=10.0,B=7.0 and C=8.0 , respectively, and by their respective direction angles with the horizontal direction =35,=110 , and =30 . The physical units of the magnitudes are centimeters. Choose a convenient scale and use a ruler and a protractor to find the following vector sums: (a) R=A+B , (b) D=AB , and (c) S=A3B+C .
A trapper walks a 5.0-km straigt4ine distance from his cabin to the lake, as shown in the following figure. Use a graphical method (the parallelogram rule) to determine the trapper’s displacement directly to the east and displacement directly to the north that sum up to his resultant displacement vector. If the trapper walked only in directions east and north, zigzagging his way to the lake, how many kilometers would he have to walk to get to the lake?
A small plane flies 40.0 km ma direction 60 north of east and then flies 30.0 km in a direction 15 north of east. Use the analytical method to find the total distance the plane covers from the starting point, and the geographic direction of its displacement vector. What is its displacement vector?
