Projectile Motion Solver

**
**Projectile Motion is the motion of an object in two directions. The object
is moving in the x-direction with zero acceleration and in the y-direction with
a constant acceleration equal to ± g.

To simplify problem solving, three assumptions are made:

- The curvature of the earth is negligible.
- The variation of the acceleration due to gravity with altitude is negligible.
- Air resistance is negligible.

The motion of a projectile is analyzed by considering the horizontal component
of the projectile's motion to be independent of the vertical component. If air
resistance is neglected, the horizontal component of motion does not change
meaning there is no horizontal acceleration and the projectile moves with a
constant speed. The vertical component of the projectile's motion is affected
by gravity and can be described by the equations for an object in free fall.
