Question

how does a kungfu master break a pile of tiles with a blow from his head? Exlpain it mathematically

Answer 1

This is because the kungfu master strikes the pile of tiles with his hand, very very fast.So, the large momentum of fast moving hand is reduced to 0, in a very very fast time. This exerts a very large force on the pile of tiles, that too on a less area of contact and this force, which is sufficient to break them apart, is transferred through the pile ,thus breaking it.
