11.The components of vector A and vector B are:

Ax = + 7.6 Bx = −3.8
Ay = -9.2 By = +4.6

Which equation describes the relationship between the two vectors?

12. A vector of components (6, 2) is multiplied by the scalar value of 3. What is the magnitude and direction of the resultant vector?

11) A = Ax+Ay = -3.8+4.6 = 0.8

B = Bx + By = -0.5 -0.5 = -1

Now 

relationship between A and B are,

A = -0.8 B


12) MAGNITUDE = 3*SQRT(36+4) =18.97

Direction = arctan(2/6) = 18.43 degrees from horizontal
