If the flare is fired at the same angle over the flat sea, Ask an Expert

Academics

A pistol that fires a signal flare gives the flare an initial speed (muzzle speed) of 145 m/s.

(a) If the flare is fired at an angle of 65° above the horizontal on the level salt flats of Utah, what is its horizontal range? You can ignore air resistance.
1 km

(b) If the flare is fired at the same angle over the flat Sea of Tranquility on the moon, where g = 1.6 m/s2, what is its horizontal range?
