Add the following 3 displacements using the head-to-tail method of adding vectors: 30 m East followed by 20 m North, and finally 15 metres NW. d Answer: total = 36.2 m, 57.6° anticlockwise from the +x-axis. 2. Strategy: 1. Draw a system of axes (x and y at right angles to each other). Take the first two vectors and draw them head-to-tail on the diagram starting from the vertex (origin) of your set of axes. 3. Determine the resultant of d, and 8, (01+2). Now determine å total by adding dj+2 to d, as in point 2. 4. Note: Any number of vectors may be added in this way. However, when adding more than two vectors, the procedure becomes time consuming and the probability of making calculation errors increases. Question: Is there another method of adding (/subtracting) vectors that is both simple and general?
