Explain Why is it difficult for a fireman to hold a hose which ejects a large amount of water at high velocity

Expert Answer:

The water exiting the hose is being pushed forward by the water behind it in the hose, 
so it pushes back on that water (and the hose). Since it is a large mass of water being 
ejected at a high speed, the impulse it feels is large and forward, and the water then 
provides a large impulse back on the hose, which makes it hard to hold
