Final answer:
To graphically find the resultant vector, you can use the head-to-tail method by drawing the given vectors and measuring the magnitude and direction of the resultant vector.
Step-by-step explanation:
To graphically find the resultant vector, we can use the head-to-tail method. Start by drawing vector A, which is 35 km at 250° N of E. Then, draw vector B, which is 15 km at 0° E of N, starting from the end of vector A. Next, draw vector C, which is 20 km at 430° S of E, starting from the end of vector B. Finally, draw vector D, which is 40 km at 280° S of W, starting from the end of vector C. The resultant vector is the vector that goes from the starting point of vector A to the end point of vector D. Using a ruler, we can measure the magnitude and using a protractor, we can measure the direction of the resultant vector.
