firemen are shooting a stream of water at a burning building using a high-pressure hose that shoots out the water with a speed of 25.0 m/s as it leaves the end of the hose. once it leaves the hose, the water moves in projectile motion. the firemen adjust the angle of elevation α of the hose until the water takes 3.00 s to reach a building 45.0 m away. you can ignore air resistance; assume that the end of the hose is at ground level.
