First, you need to know how long the object is in flight.
y=v0sin(theta)t-(.5)(g)t2
If the object's final height is the same as it's initial height, then y=0 and the above equation becomes time=((2v0sin(theta))/g)^(1/2).
Now that you know how long the object is in flight, you use the distance=rate x time.
Range= v0cos(theta) x time
Projectile speed, projectile expansion, and projectile size are a few factors that determine intermediary range of a gun shot wound.
Individuals firing missiles will use Projectile Motion equations to determine where the missile will hit, so they can fire them with the correct trajectory at the intended target. An i-phone game, Angry Birds, uses projectile motion as well.
hypothesis on projectile motion
Because a projectile by definition, is in motion.
Projectile motion has two components horizontal motion and vertical motion. Gravity affects only the vertical motion of projectile motion.
-- In what direction should a projectile be launched in order to achieve the maximum range ? -- Toward 45 degrees above the horizontal.
45 degrees is the furthest one
Some of the factors that determine the movements of a projectile include: air resistance, force of gravity, initial launch velocity, the angle a projectile was launched at, and the objects initial elevation.

Gravity
A feather falling in a vacuum is not considered as a projectile motion. Gravity, which is absent in a vacuum, is one of the components of projectile motion.
