A burning house sits on top of a 5.5-m-tall hill. The fire department's pump truck is parked at the bottom of the hill, and firefighters have dragged the nozzle end of the hose up the hill to aim it at the house. Water leaves the nozzle with a speed of 17.0 m/s. (a) What is the absolute pressure of the water in the truck's water tank? (b) The house is 6.2 m tall. Will the firefighters be able to put out the fire on the roof? (i.e., what is the maximum height above the nozzle that the water can reach?) (c) The diameter of the nozzle is 3.0 cm. If the water continues to exit at 17.0 m/s, how long will it take to empty the truck's 3800-L tank?
