Hey guys,

Im fairly new to this, but I got this question,

"Q1.A firefighter is 20m away from a burning building. She directs the fire hose at an angle of 30 degrees above the horizontal and the water has an initial speed of 30 m/s. At what height does the water hit the building?"


I tried to solve the equation using vectors, but each time i got a different answer, the ones being 9,5,20,3 and freakishly, 0m. I am stuck beyond belief :/ Anyone know what the answer would be? even though i know it sounds stupid to ask.
