I'm skeptical. If it DOES flatten that much, the time of impact is
considerably longer than it might otherwise be, thus reducing the
average force. For a complete flattening, I get an average force of
something like mv^2/(2d). With m = 50 g, v = 150 mph, and d = 4 cm,
this gives something like 3 kN, it seems to me that I can pretty
easily apply a static force of 1 kN (e.g., by standing on the ball)
and I'd expect to see very little compression. So, as I say, color
me skeptical.
