Question

Explain why is difficult for a fireman to hold a house, which ejects large amounts of

water at a high velocity?​

Answer 1

Answer:

Therefore, in order to conserve momentum, the hose tends to move in the backward direction and hence is difficult to hold, or The ejection of large amounts of water at a high velocity from a hosepipe results in the development of an equal force of reaction on the hosepipe in the backward direction.

hope this helps u

Answer 2

Explanation:

The water that is ejected out from the hose in the forward direction comes out with a large momentum and equal amount of momentum is developed in the hose in the opposite direction and hence the hose is pushed backward. It becomes difficult for a fireman to hold a hose which experiences this large momentum.
