firefighters use a high-pressure hose to shoot a stream of water at a burning building. the water has a speed of 25.0 m/s as it leaves the end of the hose and then exhibits projectile motion. the firefighters adjust the angle of elevation α of the hose until the water takes 3.00 s to reach a building 45.0 m away. ignore air resistance; assume that the end of the hose is at ground level.
