You walk 3 displacements in turn as shown in the figure: first segment A with a length of 2.25 km; then segment B with a length of 1.12 km; and finally segment C with a length of 1.4 km. You then want to find the displacement D you'd need to walk to get back to your original location. C. Find the angle that D makes with the negative y-axis. 0=? D. Find the angle that D makes with the positive x-axis. 19 8 A. Write out the x and y components of the 3 known displacements, in terms of their magnitudes and the appropriate trig function. Don't evaluate your numbers yet! Carefully check that you've used the correct trig functions and the appropriate signs for each component. B 15 B. Find the magnitude of D. (Hint: What do all 4 displacements together add up to? Use this to first find the components of D.)
