Pro Consider the three vectors, A = 2 m @30, B = 3 m @-20 and C = 1 m @120 with angles measured relative to the positive x-axis. + 2C 1A B + 1. Find R = A + B - C graphically. Report the resultant vector. 2. Find R = A + B - C by components for the coordinates shown above. Report the resultant vector. Remember: use the method described in the PHYS 152 class. 3. The drawing below shows the same three vectors in a different coordinate system. What is your expectation about the resultant (think of finding it graphically) in the new system? Will it be different from your results found above? Explain your reasoning. 4. Will finding the resultant by components produce a different result than in part 2? Explain. 5. Now solve for R = A + B - C by components for the coordinate system shown below. + TA 88 B + 6. Are the resulting vectors the same in the two coordinate system? Explain your reasoning. 7. Are the answers (the resultants) the same? If not, what changed and is there a way to make them the same? Explain. 8. On which coordinate system was it easier to find the resultant graphically? Explain. 9. On which coordinate system was it easier to find the resultant by component? Explain.
