vectors are easy once you break them down the right way.
Here is a shortcut formula i have got for you to use to find the x & y components of any vecor, once you know the magnitude and angle (theta):
to find the x component, use:
[tex][magnitude] * cos(theta)[/tex]
to find the y component use:
[tex][magnitude]*sin(theta)[/tex]
so for this question use:
[tex]y = 7 * sin(45) = 4.94N[/tex]
