Kick back animation

[Kalo]

So, I have a vehicle firing, and I want that vehicle to have some kick back every time it fires. I want a certain amount of force to be directed to the vehicle in the opposite direction it's firing at. I thought it would be something like the following, but it seems to be wrong.

this.game.add.tween(this.player.body.position).to({
    y: this.player.body.position.y - 10,
    x: this.player.body.position.x - 10
}, 0, Phaser.Easing.Linear.In, true, 0, 1000);

Anyone have any ideas?

That tween has a duration of 0 and is the same as applying the property changes directly.
