Question 1 1. Which of these equations is a case where you would NOT ever need to subtract two vectors?

Question 2 2. In a different tug of war, one team pulls with a force of 50 newtons at an angle of 30 degrees from the positive x-axis, and a second team pulls with a force of 25 newtons at an angle of 250 degrees. Use a scale drawing to determine the total force and angle applied to the central ring. (NOTE: You will need paper, a protractor and a ruler to complete this question.)

Question 3 3. If the following image is the vector F1, what would negative F1 look like?

Question 4 4. Which of the following is the meaning of a scale drawing?

Question 6 6. Which of the following is a correct example of geometric vector addition? (NOTE: In these diagrams, the BLACK arrow is the total, and the blue and red arrows are the vectors we should be adding together.)

Question 7 7. Which of the following is a correct representation of vector a minus vector b?

Question 8 8. If vector 1 has a magnitude of 3, and a direction of 30 degrees below the negative x-axis, and vector 2 has a magnitude of 4, and a direction of 80 degrees below the negative x-axis, what is vector 1 minus vector 2? (Please complete this question geometrically using paper, a pencil and a ruler.)

Question 9 9. When might you need to subtract vectors?

Question 10 10. How do you add vectors geometrically?
