Question

A krate player can easliy break the piles give reason

Answer 1

I cant get u so sure about it ,maybe! Cauze the entire momentum of the hand is reduced to zero in a short time thus large force is delivered

Answer 2

When a karate player strikes the pile of tiles with his hands, he does so as fast as possible. In other words, the time taken to strike the pile of tiles is very small . As momentum of the hand of a karate player reduces to zero, when his hand strikes the pile of tiles in very- very small interval of time,

Therefore, a very large force ( F = dp/ dt ) is exerted on the pile of tiles .

This Force is enough to break the pile of tiles.
