Firefighters are throwing a jet of water at a burning building using a high-pressure hose that gives the water a speed of 25 m/s as it comes out of the nozzle. Once it comes out of the hose, the water moves in a projectile motion. Firefighters adjust the elevation angle until it takes 3s for the water to reach a building 45 m away. Assume that the nozzle of the hose is at ground level a) Calculate the angle a b) At what height above the ground does the water hit the building, and with what vertical velocity does it do so?
