Question

What is newton second law of motion? explain how a karate player can break a slap of ice?

Answer 1

a) Newton's second law of motion states that force is directly proportional to the rate of change of momentum.

b) A karate player strikes the slab of ice very fast, so a large momentum of his hand is reduced to zero in a short interval of time which exerts a very large force on the ice to break it.
