Question

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

Answer 1

To answer this question, we first need to understand what force. In physics, a force is any interaction that, while unopposed, causes an object to change its velocity. An object with mass can change its velocity, or accelerate, as a result of a force. Intuitively, force can be described as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Complete step-by-step solution:
Newton's third law of motion – When one body produces a force on another, Newton's third law of motion asserts that the first body receives a force of equal size in the opposite direction. If object A exerts a force on object B, object B must respond with a force of equal magnitude and in the opposite direction.
When a fireman holds a hose that is ejecting massive amounts of water at a rapid velocity, the ejecting water in the backward direction exerts a reaction force on him. Because of Newton's third law of motion, this is the case. The fireman's stability suffers as a result of the backward force. As a result, he finds it difficult to maintain his balance while holding the hose.
So, we conclude that, according to the third law of motion, when the fireman holds the hose, it produces the opposite reaction. The fireman becomes unsteady as a result of this backward and equal reaction, and it becomes difficult for him to grip the hose.

Note: Newton's laws of motion are three laws that describe the relationship between an object's motion and the forces acting on it in classical mechanics. Unless it is acted upon by an external force, the first law asserts that an object either remains at rest or continues to travel at a constant pace.
