Question

A firefighting crew uses a water cannon that shoots water at 29.0 m/sm/s at a fixed angle of 48.0 ∘∘ above the horizontal. The firefighters want to direct the water at a blaze that is 11.0 mm above ground level.

How far from the building should they position their cannon? There are two possibilities (d1<d2d1<d2); can you get them both? (Hint: Start with a sketch showing the trajectory of the water.)
