To determine the vector , given the vectors and in Fig. 3-35.
Step-by-step explanation
Step 1.
To get the difference between vectors and ,
resolve the and components of each vector
get the difference between the and components of the two vectors
use the Pythagorean theorem and the inverse tangent equation to calculate the magnitude and the direction of the resultant vector.
Recall that the and components of any given vector can be calculated as follows.
where is the magnitude of the vector and is the angle that the vector makes with the axis.
The magnitude of vector is and is . Meanwhile, the magnitude of is and is or as measured from the axis.
From these, write the equations for the components of the vectors.
