You can do like:

warning code can have compailing errors!

var thefoot : GameObject;
var adjustforce = 10;
private var theforce = 0;
private var dir : Vector3;

function FixedUpdate () {
	theforce = thefoot.rigidbody.velocity * adjustforce;
	dir = thefoot.transform.TransformDirection (Vector3.up); //blue arrow
	rigidbody.AddForce (dir * theforce);
}
