Question

why is it difficult for a firefighter to hold a hose that ejects large amounts of high-speed water?
Explain using Newton's laws

Answer 1

It is difficult for a Fireman to hold a hose which ejects large amount of water at high velocity because of the third law of Newton which states, for every action there is an equal and opposite reaction
As the hose which ejects a large amount of water moving forward has the force which also react the force in the backward direction that's why Fireman hold the host tightly

HOPE THIS MIGHT BE HELPFUL

Answer 2

A force is a push or a pull that acts upon an object as a results of its interaction with another object. ... These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.

In this case the same thing happens .
For the action (ejection of high amount of high speed water ) there is an equal and opposite reaction( throw back of the hose) . The hose comes at the same speed and force in the opposite side of a high speed ejecting water. So it becomes very difficult for a firefighter to hold a hose which comes with very huge force as same of the water.

HOPE IT HELPS YOU .
