Question

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

Answer 1

Answer:

order to conserve momentum, the hose tends to move in the backward direction and hence is difficult to hold, or The ejection of large amounts of water at a high velocity from a hosepipe results in the development of an equal force of reaction on the hosepipe in the backward direction.

Explanation:

Answer 2

Answer:

When a fireman holds a hose, which is ejecting large amounts of water at a high velocity, then a reaction force is exerted on him by the ejecting water in   the backward direction. This is because of Newton's third law of motion.

Hence, it is difficult for him to remain stable while holding the hose
