Physics Question need help?

A firefighter arriving at a fire finds the closest she can get to the fire is about 50 feet away. What angle should she set the fire hose to if the water pressure can hold an initial velocity of 115ft./sec and she needs to have the water enter a second story window that is about 15 feet from the ground?Please help me. And also i want the calculation.

Answer:

Do you have a pool? There is a kind of sump-pump that you can install to keep your home wet during the fires. I saw a home on the news that was spared due to using the pump. Other then that, you should be clearing brush around your home and be weary of fire hazards.
It depends. If the goggles came with the gun, they will probably work. The safety glasses do not work at all. Paintball masks work, but get fogged up.
TC is spot on! Our aggressive saving of natural forests has created a problem. For the last 50 years we have aggressively put out ALL fires as soon as possible. Smokey has informed you the you can prevent forest fires. Well, we now have huge areas of woodland, with no cleared areas interspersed. This means when a fire does start during dry and windy conditions, the fires are enormous. Had we let some of the previous fires burn a bit, there would be areas that would stop subsequent fires because there is no fuel. I do know the DNR is realizing they made a mistake no letting nature take it's course.
