Answer:
As the firefighter is holding the hose, the backward force is also applied to her. In order to keep her balance, i.e. to be in translational equilibrium, the vector sum of the forces has to be zero, i.e. all forces cancel out. Hence, she has to lean forward for there to be a forward force to maintain her balance.
