Homework Help: Two dimensional projectory

  1. Oct 14, 2014 #1
    A fireman is standing on top of a building 20m high, he wants the water from the hose to reach the burning wall at the same level above the ground as he is standing. Horizontal velocity is 12m/s. At what angle must he aim the hose relative to the horizontal?

    Welcome to PF!

    Please take a moment to read the guidelines of PF. This looks like a homework assignment. We have a template or homework questions where you describe the problem, show relevant formulas and show your work. We can't do your homework and we can't help until you show us some work.

    Lastly, I think your title should be trajectory not projectory. It helps to have descriptive titles.
