Question

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

Answer 1

Explanation:

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.
