Let vector A equal 120 grams at 0 degrees and vector B equal 90 grams at 90 degrees. Establish a scale to represent the two vectors on a sheet of graph paper. Use the Head to Tail method to find the resultant of the addition of Vector A and Vector B.
On a grid with increments of 30, vector a would be a line from the origin to point (120, 0), and vector b would be a line from the origin to point (0,90). Placing the start of vector b at point (120, 0) causes the end point to be on the point (120, 90). Therefore, the displacement of vector a plus vector b is <120, 90>.
