Why might it be hard for the firefighter to hold the hose
steady when the water gushes out of the hose? Think
about the law of conservation of momentum.
When you think about the conservation of momentum, there is always some force going in both directions. The mass and velocity of the water coming out of the fire-fighter's hose makes the tube want to move backwards, because there is a force pushing the hose in the opposite direction that the water itself is going in. It's the same as the gun and bullet problem. There is a recoil in the other direction in the gun after a bullet is shot because there is a backward force pushing on the gun itself from the forward force of the bullet.

Don't copy me!!!!!
To understand why it might be hard for a firefighter to hold the hose steady when the water gushes out, we need to consider the law of conservation of momentum. According to this law, the total momentum of a system remains constant unless acted upon by an external force.
When water flows out of the hose at a high speed, it possesses momentum due to its mass and velocity. As the water exits the hose, it imparts a backward momentum on the firefighter, as per Newton's third law of motion (every action has an equal and opposite reaction).
Since the water has a considerable mass and velocity, the momentum it carries can exert a significant force in the opposite direction when it leaves the hose. This backward force acts on the firefighter, potentially causing them to lose their balance or struggle to hold the hose steady.
Furthermore, the force exerted by the water can create a strong reaction force on the nozzle, making it difficult to control its direction. The stronger the flow of water, the more challenging it becomes to counteract and stabilize the momentum produced.
To overcome these difficulties, firefighters are trained to use techniques like bracing their bodies, using proper grip and posture, and utilizing stabilization devices to control the hose effectively and maintain their balance even when the water gushes out with substantial force.
