Vector Nature of Force

Question is in attachment

 

So the formula I used was F= ma = F= mdelta v / t

 

10i + 20j = 5 kg(Vf-(-5i+30j)/10

I got 10i +20j = 1/2vf( -5/2i+15j)

= (15i + 70j)m which is C.

However the question says the object is located in the origin of reference frame and asks to find the position of the object which I don't understand how to do :/

 

 

Oh a piece of the question got cut off. The question is "What will be the position 10 seconds later"?

What it is telling you is that at the "starting time" the object is located at the origin of some frame of reference.

Oh so that's what it meant. Thanks for the clarification...!!
