Question

A word on notation:
So far we have been expressing vectors and their components as ~v = ~vx + ~vy. This notation is
acceptable but you may run into something that looks like this: ~v = 〈vx, vy〉. This notation is
more formal, but accomplishes the same thing. In this new notation, the wolf problem above
would look like this:
Σ ~F = 〈ΣFx, ΣFy〉
= 〈F1x + F2x + F3x + F4x, F1y + F2y + F3y + F4y〉
In place of all of the Fix and Fiy ’s, you would put the numbers you found in the problem and
calculate the same way.
