Question

When vector vector A is added to vector Vector B, the resultant is vector vector R such that vector R is equal to vector A plus vector B. This resultant vector has components vector R sub x is equal to vector A sub x plus vector B sub x and vector R sub y is equal to vector A sub y plus vector B sub y. What is the y-component of the resultant vector vector R is equal to vector A plus vector B when you add vector A and Vector B?

Answer 1

Answer:

Step-by-step explanation:

We have any vector in two dimension will have both vertical and horizontal components.

When two vectors say $A= xi+yj and\\B = zi+wj$are added we get

resultant as

$R=(x+z)i+(y+w)j$

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.
