8m
Explanation:
The magnitude m of a vector (x, y) is given by
m =
-------------------------(i)
where;
x and y are the x- and y- components of the vector.
From the question;
m = 10m
x = 6m
Substitute these values into equation (i) as follows;
10 =![\sqrt{6^2 + y^2}](/tpl/images/1362/8251/51d5d.png)
Solve for y;
Find the square of both sides
10² = 6² + y²
100 = 36 + y²
y² = 100 - 36
y² = 64
y = √64
y = 8
Therefore, the y-component of the position vector is 8m
