Two force vectors,
F1 = (-3.0 N) x-hat + (-2.5 N) y-hat
F2 = (-6.0 N) x-hat + (3.5 N) y-hat
are applied to a particle. What third force F3 would make the net force on the particle zero?

With that vector equation, you can solve for the a and b components of F3 by equating the x direction and the y direction values...
0 = -3.0 +(-6.0) + a [N]
Total force in the x direction is 0 or -3 - 6 + a, newtons,
same for Y, then you have your F3 force
The sum of the components in the X-direction is zero
The sum of the components in the Y-direction is zero
(all the xroofs have to equal zero)
(all the yroofs) have to equal zero)
solve for the components of the third force
So is that a yes or a no to being <9,-1> For F3?
That looks good
Did you do a section on vectors before this? if i remember i think there was in physics 1, maybe not
