Explanation:
Because, 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.

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.
