Projectile motion is a form of motion moves along a curved path under the action of gravity only.
Vertical Displacement at Time: Δy=Vy0t - 1/2gt2
where, t = Time, g = Acceleration of Gravity, Vy0 = Initial Vertical Velocity, Δy = Vertical Displacement at Time.
For example, when Initial Vertical Velocity is 50m/s, The acceleration of gravity is 9.8m/s2, the time is 3, then the displacement is 105.9m.
