1.If there were a set-up with three vectors all lying in the rst quadrant, in which quadrant must the equilibrant be? Why?
2.What sources of error could exist to account for differences between the standard values and the graphical and experimental results?
3.The direction of the vector (the angle) was always measured counter clockwise from the positive x axis. If the angle were instead measured clockwise from the positive y-axis, how would that effect the way we determine the x- and y-components of the vector?
4.Within the force table set-up why must we experimentally determine the equilibrant force in order to obtain a value for the resultant force vector?

In this lab you will be given two different sets of vectors to add together. In Activity 1, you will add position vectors: in Activity 2 you will add forces. Vector addition is an important concept in physics. To be well prepared for the lab you need to solve the following example. Make sure to show all your work in detail. Write the equations first, and then plug in the numerical values. Do not forget to do unit conversions. Use...

Consider the three displacement vectors A = (3i - 3j) m, B = (i - 4j) m, and C = (2i + 5j) m. Use the component method to determine (a) the magnitude direction of the vector D = A + B + C and (b) the magnitude and direction of E = -A - B + C.
