**Unformatted text preview: **resultant 4.2; bearing 346 o c) 6 units south followed by 12 units along a bearing of 300 degrees resultant 10.4; bearing 90 o 4. An object moves 90 meters due south (bearing 180 degrees) turns and moves 50 more meters along a bearing of 240 degrees. a) Find the resultant of these two displacement vectors. 122.9 b) What is the bearing from the end point back to the starting point? 200 ◦ Writing activity: How does a vector differ from a line segment? A possible answer would be “A vector has both magnitude and direction while a line segment has only magnitude.” Use the law of cosines to find the resultant: 347 km Find ∠ x using the law of sines: 54.3 o Add 20 o to 54.3 o giving 74.3 o for the bearing from the starting point to the ending point. 20 o x...
