Unformatted text preview: for i and ii below. a) 9 units north followed by 6 units along a bearing of 75 degrees b) 8 units east followed by 10 units along a bearing of 170 degrees c) 6 units south followed by 12 units along a bearing of 300 degrees 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. b) What is the bearing from the end point back to the starting point? Writing activity: How does a vector differ from a line segment?...
