text: whats the formula for figuring the impact weight of an egg going 60 miles an hour hitting a brick wall? and lets say the egg weighs 8 ounces... isn't it illegal for eggs to travel that fast? especially since the presence of a brick wall strongly suggests that this is taking place in an urban area.   you have a lot of unaddressed variables here: at 8 ounces this is an uncommonly large egg. (it could of course be an ostrich egg, which might account for its extreme speed and size.)    which part of the egg hits the wall first?   eggs are of course ovoid, and the lateral surface would present a greater surface area to the wall.    is the egg still inside the ostrich?   that would certainly skew your results, and would probably skew the ostrich.      if it isn't an ostrich egg, the formula below is less applicable,  since present terms are dependent on the mass/viscosity of ostrich eggs.    however, all things being equal, where:   e is the egg's weight in ounces,   m is its velocity in miles per hour c is the clot who threw it in the first place.    the requisite formula proves to be e=mc2  q.e.d.
