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

 

Answer

By Newton’s Third law of motion, every action has an equal and opposite reaction.

When a hose pipe ejects a large amount of water in the forward direction, it exerts a large amount of backward reaction force.

 

Due to this backward reaction, the hose pipe tends to move backwards.

This backward movement makes it difficult for the fireman to hold the hose pipe and the fireman has to hold the hose pipe strongly.
