Homework Help: physics

Posted by corrina on Saturday, January 26, 2013 at 1:26am.

Firemen are shooting a stream of water at a burning building. A high-pressure hose shoots out the water with a speed of 24.0{\rm m}/{\rm s} as it leaves the hose nozzle. Once it leaves the hose, the water moves in projectile motion. The firemen adjust the angle of elevation of the hose until the water takes 3.30{\rm s} to reach a building 45.0{\rm m} away. You can ignore air resistance; assume that the end of the hose is at ground level.
