Problem 4: Consider the following four vectors: • 12.0 cm to the right at 23◦ above the horizontal • 31.0 cm to the left at 67◦ above the horizontal • 8.40 cm to the left at 23◦ below the horizontal • 24.0 cm to the right at 67◦ below the horizontal (a) Sketch a graph showing all four vectors with their tails at the origin. (b) Find the vector sum of the four vectors by resolving each one into components. Express your answer in terms of the magnitude of the resultant vector and the angle it makes with the positive x-axis. (c) Explain how you can simplify the calculations by choosing particular directions for the x and y axes, and state what directions you choose. (d) Find the vector sum relative to your new axes, and show that it is the same resultant vector that you calculated in part (b)

Consider two force vectors in the xy-horizontal plane. Suppose a force of 18.7 N pointing along the +x-axis is added to a second force of 20.1 N directed at 55 degrees to the +x-axis , also in the horizontal plane. Find the resultant vector for this sum.
Four displacement vectors, A, B, C, and D, are shown in the diagram below. Their magnitudes are: A = 14.6 m, B-11.0 m, C-12.0 m, and D-24.5 m, what is the magnitude and direction of the resultant vector sum of A, B, C, and D? Give the direction as an angle measured counterclockwise from the +x direction. How do you add vectors algebraically? Watch signs of components. m direction +y 20.0° +X 35.0 50.0
