A bouncing ball that drags and drops

1

I am using the AS from this tutorial on a bouncing ball that you can drag & drop

http://orangesplotch.com/blog/flash-bouncing-ball-tutorial/

I have added a basketball net mc that is stopped on frame1 that is a frame by frame animation of the net expanding. I am trying to figure out how to realistically cause the animated net to play when the basketball is dragged & dropped into the net.

on(press) {
    this._freefall  = false;
    this._momentumY = 0;
    this.startDrag(false);
}

on(release, releaseOutside) {
    this._freefall = true;
    this.stopDrag();
}

onClipEvent(load) {
    this._freefall        = true;
    this._momentumY       = 0;
    this._accelerationY   = 2.0;
    this._floorElasticity = 0.75;
    this._floorY          = 290;
    this._bounceThreshold = 3;
}

onClipEvent(enterFrame) {
    if (this._freefall) {
        this._y         += this._momentumY;
        this._momentumY += this._accelerationY;
        
        // bounce it off the floor if it has hit it
        if (this._y > this._floorY) {
            this._y = this._floorY;
            this._momentumY = -(this._momentumY * this._floorElasticity) + this._bounceThreshold;
            
            // keep it from jiggling infinitely
            if (Math.abs(this._momentumY) <= this._bounceThreshold) {
                this._momentumY = 0;
            }
        }
    }
}
