That resistive force is not the only force acting on the object (otherwise it'll just sit there). Don't forget gravity.

It moves along the x-axis...I forgot to mention that. So gravity is not taken into consideration?

If the object is initially at rest in a frame where the only force acting is proportional to velocity squared, then yes, it is obvious that the particle won't do anything. Somehow, I suspect that the question wan't meant to be that trivial.

I think that velocity to be v0, not zero. Otherwise, the problem is trivial. I just wanted to check and make sure I wasn't missing anything
