    How fast does a 4000 lb vehicle need to travel in order to propel/move a 256 lb object 69ft after striking it?

    Not enough info provided - what type of surface is this on? If on ice, the 4000 pound vehicle need barely be moving at all. I have to wonder if you are asking about a car striking a person - if so, the police have empirical models for estimating such things.
