LinearVelocity is limited?

Hello guys,


I'm try to use LinearVelocity (Body atribute) to move my object (spaceShip) . My game is based in gravity, using LinearSpeed, but, this appears to be limited.


My code to move:


public static void angleMove(GameObject gameObject)
            float vx = 0;
            float vy = 0;
            if (gameObject.Body.LinearVelocity.X > gameObject.MaxSpeed * -1 && gameObject.Body.LinearVelocity.X < gameObject.MaxSpeed)
                vx = (float)(gameObject.Acceleration * Math.Sin(gameObject.Body.Rotation));
            if (gameObject.Body.LinearVelocity.Y > gameObject.MaxSpeed * -1 && gameObject.Body.LinearVelocity.Y < gameObject.MaxSpeed)
                vy = (float)(gameObject.Acceleration * Math.Cos(gameObject.Body.Rotation)) * -1;
            gameObject.Body.LinearVelocity += new Vector2(vx, vy);


If a variable Vector2 is used to speed up (sum Body.Position and Speed), it works, but, it lost the physics effects (collision)...


What can i do to raise my speed using LinearVelocity, my max speed in the code is 300f...


Obs: Sorry my english :) Brazilian here
