🤓 Based on our data, we think this question is relevant for Professor Rodriguez's class at FIU.

# Solution: A pistol that fires a signal flare gives the flare an initial speed (muzzle speed) of 126 m/s.(a) If the flare is fired at an angle of 55.0° above the horizontal on the level salt flats of Utah what is its horizontal range? You can ignore air resistance.(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?

###### Problem

A pistol that fires a signal flare gives the flare an initial speed (muzzle speed) of 126 m/s.
(a) If the flare is fired at an angle of 55.0° above the horizontal on the level salt flats of Utah what is its horizontal range? You can ignore air resistance.
(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?
