After Linear Impulse stops

I applied a Linear Impulse to my object.

object:applyLinearImpulse( 0, 4, obect.x, object.y )   

Is there a way to listen for when the object stops moving? If the object was a square and the linear impulse sent the square straight up, how do I set up a listener for when the square stops? [import]uid: 14218 topic_id: 13326 reply_id: 313326[/import]

Any ideas?
