Projectile motion (Šikmý vrh)
A particle (a projectile) is thrown near the Earth's surface, and it moves along a curved path under the action of gravity only.
Let the projectile be launched with an initial velocity v0 with the initial launch angle . At any time t the projectile's horizontal and vertical displacement are
How far it will travel?
Note that we have neglected air resistance on the projectile.
