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. Im stuck beyond belief :/ Anyone know what the answer would be? even though i know it sounds stupid to ask.
