A firefighting crew uses a water cannon that shoots water at 26.0 m/s at a fixed angle of 49.0° above the horizontal. The firefighters want to direct the water at a blaze that is 12.0 m above ground level. How far from the building should they position their cannon? There are two possibilities (d < d2), can you get them both? (Hint: Start with a sketch showing the trajectory of the water.)
