Answer 2

${\textbf{\underline{why a karate player can break a pile of tiles in a single blow??}}}$

A karate player can break a pile of tiles with a single blow because he strikes the pile with his hand very fast. In doing so the large momentum of his hand is reduced to zero in a very short time. This exerts a large force on the pile of tiles which is sufficient to break them apart.
