Question

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

3) From a rifle of mass 4 kg, a bullet of mass 50 g is
fired with an initial velocity of 35 m/s. Calculate the
initial recoil velocity of the rifle​

Answer 1

Answer:

2)It is difficult because of the Newton's third law which states that every reaction has a equivalent opposite reaction.

As the water pushes the hose backward in the same force it is difficult for the fireman to hold the hose in which ejects large amount of water with high velocity.
