Question

A firefighting crew uses a water cannon that shoots water at 30.0 m/s at a fixed angle of 50.0 ∘ 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 (d1<d2); can you get them both? (Hint: Start with a sketch showing the trajectory of the water.)
