(a) Define momentum. Write its SI unit.
(b) How much momentum will an object of mass \(12\ kg\) transfer to the floor, if it falls from a height of \(5\ m\) (\(g\ =\ 10\ m/s^2\))?
(c) Explain how a karate player can break a pile of tiles with a single blow of his hand?

(c) Explain how a karate player can break a pile of tiles with a single blow of his hand?
a. The momentum of an object is the and has the direction. SI unit of momentum is .
b. The final velocity of the object is. \(m/s\).
The momentum of the object is. \(Kg\ m/s\)
c. The karate player strikes the pile of tiles with his hand very fast. In doing so, the large momentum of a fast-moving hand is in a . This exerts a on the pile of tiles which is sufficient to break them.
