    I want to throw an object in Box2d by applying a force vector, But it is limited to a certain velocity even if I Apply Force by a very high value? How can I achieve this ? For Ex:- I have to fire a bullet at a very high speed.

    var force = new Box2D.Common.Math.b2Vec2(-700,+500);
            this.body.ApplyForce(force , this.body.GetPosition());

    Even if I set the value to (-7000,+5000) there is no effect beyond this. Please help.

    I have figured it out that the Box2D.SCALE factor has to be set to get the desired output. As in my project canvas size is 1920 by 1080 and Box2D.SCALE=0.1, that's what creates the drawing area very big that simulate high velocity very slowly. So, to overcome that I have set it to 0.05 Which scaled down my whole game and Now it can make an object seems to travel very fast at the same velocity.
