M2: general motion vectors

so, when you integrate V(velocity) to get S(displacement) and you've got the general formula s = i + j + c

is that in respect to the origin?

and when you sub i and j of the position vector into the equation when t = 0 to get c, what you get is the displacement in respect to that specific point (in this case, the starting point)?

thanks

If the velocity is w.r.t origin then the integral of that will give the displacement w.r.t origin.
t=0t=0 will give the initial displacement.

so I was right?

Mostly, yes.
