Explanation of why it is difficult for fireman to hold hose pipe ejecting water with high velocity

Описание: It is difficult for fireman to hold the hose pipe. When water come out from hose pipe, it come with very high speed, and forward force is applied on the water by hose pipe. According to Newton's third law of motion, the backward force is applied by water on the hose pipe ( reaction: force in backward direction on the hose pipe by the water). Due to this large force, fireman find it difficult to hold the hose pipe.
