(a) Define momentum. Write its SI unit.
(b) How much momentum will an object of mass \(8\ kg\) 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.
