XXXXXXXX SOLUTION FOUND, WAS JUST TO ZERO THE VECTORS XXXXXXXXX

I have an almost done script here, it works almost fine but when I launch the model its behave isnt what I expect.

works this way: the object has this script attached and my character, when collide with its child collider is able to pick it up, it does work well, and then, he is up to launch it but the physics isnt work the way I want.

here it is:

I was reading about possible solutions for this issue, one of then is probably "Force.Impulse" other is "vector3.normalize".

since 22 days ago I knew about nothing about programming, I really dont know how to appy it, can anybody help with this??!??!?

thanks alot in advance!

 var playerHand : Transform;

 var pegou = false;

 var soltou = false;

 var upforce = 6000.0;

 var frontforce = 3000.0;





function OnTriggerStay (other : Collider) {



if(other.transform.tag == "Player"   && Input.GetButton("Fire1")){

    pegou = true;

    timeDelay = 0;

 }

    }



    function Update() {



    if (pegou){



    var colisorzao = transform.parent;

    colisorzao.parent = playerHand;

    colisorzao.rigidbody.isKinematic = true;

    colisorzao.rigidbody.detectCollisions = false;

    colisorzao.position = playerHand.position;

    colisorzao.rotation = playerHand.rotation;

 }

 if (pegou && Input.GetButton("Fire2")){



pegou = false;

timeDelay = 0.0;

soltou = true; 



}



if(soltou){



colisorzao = transform.parent;

colisorzao.rigidbody.isKinematic = false;

colisorzao.rigidbody.detectCollisions = true;

transform.parent.rigidbody.AddRelativeForce (0, upforce , frontforce);

colisorzao.parent = null;



}

}



function segurar () {

 return pegou;



}



function soltar (){

 return soltou;

}
