1. When finding your resultant vector for a-d you were using the graphical method of resolving vectors. However, you could solve using more direct mathematical equations. Give the formula and explain how you would find the resultant vector’s magnitude using these calculations.

2. Solve for the length your resultant vectors a and d mathematically below and show your work in the space provided.

Vectors Work to Solve for Resultant Length Answer
a. a x =0, a y =10 angle 90 and a x =9, a y =0 angle 0
d. a x =7, a y =7 angle 45 and a x =8, a y = -6 angle -37
3. You can also solve for the angle of your resultant vector mathematically, describe and give the formula for how to do this.

4. Solve for the angle of your resultant for vectors a and d mathematically below and show all work in the space provided.
Vectors Work to Solve for Resultant Angle Answer
a. a x =0, a y =10 angle 90 and a x =9, a y =0 angle 0
d. a x =7, a y =7 angle 45 and a x =8, a y =-6 angle -37
5. A helicopter flies 25 km north, 5 km east, then 5 km S, then 15 km W. What is the resultant displacement and direction of the helicopter? Solve using graphical or mathematical methods. Be sure to either show work or explain your graphical methods.

6. What are some advantages of using the graphical method of vector resolution?

7. What are some disadvantages of using the graphical method of vector resolution?

8. Compare solving vectors graphically in the simulation to solving mathematically. Justify which method you think is the most beneficial to use.

9. Does this experiment show anything about God’s order and design for the earth and universe?  Please explain.

Conclusion (30 points):
? Answer the following questions in full sentences.
? Helpful tip: someone should be able to read ONLY your conclusion and tell what you thought was going to happen, what actually happened, and why it happened.  It should show complete understanding of the concepts of this lab. Use the three questions below to form your conclusion.

1. What was your hypothesis and was it correct? (2-3 sentences)

2. How do you know your hypothesis was correct? Use relevant data/observations to support your answer. (3-5 sentences)

3. Go back and read the goals for this lesson at the top of this template. Form a summary statement for each goal, showing you understand and have met the goals of this lab.  Be sure to explain all major concepts and relationships presented in this lab. (3-5 sentences)
