Question

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

Answer 1

When the fireman holds the hose, it has an opposite reaction according to the third law of motion. ... Thus, due to the opposite reaction of the water with high velocity a fireman finds it difficult to hold the hose.

Answer 2

Heya mate your answer is:


According to Newton’s third law of motion when a fireman holds a hose, which is ejecting large amounts of water at a high velocity, the reaction force is exerted on him by the ejecting water in the backward direction. As a result of the backward force, the stability of the fireman decreases. Hence, it is difficult for him to remain stable while holding the hose.
So we can say that it is difficult for a fireman to hold a hose, which ejects large amounts of water at a high velocity due to the backward force applied by ejected water.
