1) The vector sum of three vectors gives a resultant equal to zero. what can you say about the vectors?
2) Vector is 3.00 units in length and points along the positive xaxis. Vector is 4.00 units in length and points along the negative yaxis.Use graphical methods to find the magnitude and direction of the following vectors:
A) A+B
B) AB
C) A+2B
D) BA

bobpursley,
1. The vectors are equilibrants.
2. this has to be done graphically, it cant be done here. http://hyperphysics.phyastr.gsu.edu/hbase/vect.html#vec5
