A firefighter directs a horizontal stream of water toward a fire at an angle of 40° measured from the horizontal. The fire hydrant and hose deliver 91 gallons per minute (1 gal/min = 6.31 cross 10-5 m3/s),and the nozzle projects the water with a speed of 7.3 m/s. How much horizontal force must the firefighter exert on the hose to keep it stationary?
