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 Č 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. Ď 0=? 19⁰ 8⁰ 10 B Ā 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! 15⁰ Carefully check that you've used the correct trig functions and the appropriate signs for each component. 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.) C. Find the angle that D makes with the negative y-axis. D. Find the angle that D makes with the positive x-axis.
