Q. A fireman clings to a vertical ladder and directs the nozzle of a hose horizontally toward a burning building. The rate of water flow is 5.420 kg/s, and the nozzle speed is 16.0 m/s. The hose passes between the fireman's feet, which are 1.3m perpendicularly below the nozzle. Select the origin to be inside the hose between the fireman's feet. What torque must the fireman exert on the hose? That is, what is the rate of change of angular momentum of water?
