Detailed Solution

Newton’s third law of motion is applicable.
When a fireman directs a large amount of water at high velocity on a fire from a hose pipe, they must hold the hose pipe firmly because it has a tendency to back up. According to Newton's third law of motion, the backward movement of the hose pipe is produced by the backward reaction of the force of water rushing out through it in the forward direction at a high speed.
