A fire hose can expel water at a rate of 9.5 $\mathrm{kg} / \mathrm{s}$ (150 gallons/ minute) with a speed of 24 $\mathrm{m} / \mathrm{s} .$ How much force must the fire-fighters exert on the hose in order to hold it steady?

The water coming from a fire hose produces a tremendous amount of force. If not careful, a firefighter may not be able to hold the fire hose and hurt himself or somebody. Consider a fire hose having an inner diameter of 75 mm. Water is coming out with a speed of 12.0 m/s and at a rate of 1500 kg/min . How much force does it take to hold the fire hose in place?
