Question

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

Answer 1

Answer:

Explanation:

By Newton's Third Law, the force at which the water is forced out of the hose has to equal the force which the water pushes back. The principles also apply to momentum, the amount (mass) of water being shot out (velocity) produces a recoil on the hose. To stop the hose from moving, the firefighter has to supply his own force on the hose, and given how much water and how power it is being shot out of the hose, the firefighter must exert a large quanity of force to counter the hose's recoil.

Answer 2

Explanation:

When large amount of water is ejected from a hose at a high velocity, according to Newton’s Third Law of Motion, water pushes the hose in backward direction with the same force. Therefore, it is difficult for a fireman to hold a hose in which ejects large amount of water at a high velocity.
