Question

A position vector in the first quadrant has an x-component of 18 m and a magnitude of 30 m. What is the value of its y-component?

Answer 1

The value is 24meters

Step-by-step explanation:

Using

r= xi+yj

To get the magnitude of vector x

We say

/r/= √x²+y²

So

30²= √18² + y²

y= √576

Y= 24m
