Question

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

Answer 1

•because every action has equal and opposite reaction

•so when water comes out with high velocity the hose goes back

Answer 2

This is based on Newton’s law that every action has an equal and opposite reaction. When the water is sprayed from the hose at a high velocity, the force makes the fireman jump back
