A projectile is an object upon which the only force acting is gravity. There are a variety of examples of projectiles: an object dropped from rest is a projectile (provided that the influence of air resistance is negligible).
The main criteria of a projectile object are:
The horizontal and vertical components of projectiles are completely independent of each other.

Vertical Velocity at Time:
Vy = Vy0 - gt
Initial Vertical Velocity:
Vy0 = Vy + gt
Acceleration of Gravity:
g = Vy0 - Vy /t
t = Vy0 - Vy / g
Vy = Vertical Velocity at Time
Vy0 = Initial Vertical Velocity
g = Acceleration of Gravity
t = Time.
Projectile motion is a part of parabolic motion. Parabolic motion has the following properties:
They are under constant acceleration.
There exists a non-zero component which is perpendicular to the acceleration so as to produce a parabolic path. If this condition is not satisfied, the motion is actually a linear motion.
By definition, a projectile has only one force acting upon - the force of gravity.
Calculate the Vertical Velocity at Time (Vy) for a projectile object by the given details.
Initial Vertical Velocity (Vy0) = 40 m/s
Acceleration of Gravity (g) = 10 m/s2
Time (t) = 2 s
Vy = Vy0-gt
Vy = 40 -10*2
Vy = 40 -20
Vy = 20m/s
Vertical Velocity at Time (Vy) = 20m/s
