**j**(vertical, right?). Then a total of 12.0N

**i**(horizontal) acts on it for 5 seconds. What is the objects final velocity.

I know that the equation is Ft=mvf-mvi

I could just plug everything in, but what's bothering me is the fat that the mass has an vertical velocity and the force is acting on it horizontally. Am I reading this wrong or is this the case?

If so, how do I go avout finding what I need to plug in.

My work:

Ft=mvf-mvi

(12N)(5s)=(5)(vf)-(5)(7)... then solve for vf, but that seems too easy.
