Question

explain , why is it difficult for a fireman to hold a hose , which ejects large amounts of water at a high velocity.

Answer 1

It is difficult for the Fireman to hold the hole because when the water comes out from the nozzle it comes with a very high velocity and providing a very great thrust to the Fireman since it is difficult for him to hold it

Answer 2

Explanation:

The water that is ejected out from the hose in the forward direction comes out with a large momentum and equal amount of momentum is developed in the hose in the opposite direction and hence the hose is pushed backward. It becomes difficult for a fireman to hold a hose which experiences this large momentum.
