A karate player can break a slab of ice or pile of tiles with a single blow. How is that possible?
This is physics!!A karate master can break a pile of? tiles or a slab of ice with a single blow because he strikes it very fast and in the process produces a lage momentum of his hand which is reduced to zero in a very short time when his hand strikes the tiles.this exerts a large force on the pile of tiles thus breaking it.
