Answer:
Step-by-step explanation:
We have any vector in two dimension will have both vertical and horizontal components.
When two vectors say [tex]A= xi+yj and\\B = zi+wj[/tex]are added we get
resultant as
[tex]R=(x+z)i+(y+w)j[/tex]
In other words when A has x component as x and y component as y, and similarly when B has x component as z and y component as w
the sum will have horizontal component as x+z and vertical component as y+w
Thus we have
y component of the resultant vector R = y component of A + y component of B.
