Help me solve this problem!!

Question

Vector A has a magnitude of 8.00 units and makes an angle of 45.0° with the positive x-axis. Vector

B also has a magnitude of 8.00 units and is directed along the negative x-axis. (Show work!)

a) Using graphical methods, find the vector sum A + B

b) Using graphical methods, find the vector difference A − B.

Answer 1

Vector A is <8/sqr2, 8/sqr2>

vector B is <-8, 0>

A+B = <8/sqr2 -8, 8/sqr2> = about <-2.3,5.7>
