The image above represents final velocity. To calculate final velocity, three essential parameters are needed and these parameters are initial velocity (u), acceleration (a) and time (t).
The formula for calculating final velocity:
v = u + at
Where;
v = Final Velocity
u = Initial Velocity
a = Acceleration
t = Time
Let’s solve an example;
Find the Final velocity when the initial velocity is 12, acceleration is 9, and the time is 24.
This implies that;
u = Initial Velocity = 12
a = Acceleration = 9
t = Time = 24
v = u + at
Then, v = 12 + (9 x 24)
v = 12 + 216
v = 228
Therefore, the final velocity is 228 m/s.
Calculating the Initial Velocity when the Final Velocity, the Acceleration and the Time are Given
u = v – at
Where;
u = Initial Velocity
v = Final Velocity
a = Acceleration
t = Time
Let’s solve an example;
Find the Initial Velocity when the Final Velocity is 32, the acceleration is 12 and the time is 2.

This implies that;
v = Final Velocity = 32
a = Acceleration = 12
t = Time = 2
u = v – at
So, u = 32 – (12 x 2)
u = 32 – 24
u = 8
Therefore, the initial velocity is 8 m/s.

Calculating the Acceleration when the Final Velocity, the Initial Velocity and the Time are Given
a = v – u / t
Where;
a = Acceleration
u = Initial Velocity
v = Final Velocity
t = Time
Let’s solve an example;
Find the acceleration when the final velocity is 50, the initial velocity is 24 and the time is 12.
This implies that;
u = Initial Velocity = 24
v = Final Velocity = 50
t = Time = 12
a = v – u / t
That is, a = 50 – 24 / 12
a = 26 / 12
a = 2.16
Therefore, the acceleration is 2.16.
Calculating the Time when the Final Velocity, the Initial Velocity and the Acceleration are Given
t = v – u / a
Where;
t = Time
u = Initial Velocity
v = Final Velocity
a = Acceleration
Let’s solve an example;
Find the time when the final velocity is 40, the initial velocity is 20 and the acceleration is 10.
This implies that;
u = Initial Velocity = 20
v = Final Velocity = 40
a = Acceleration = 10
t = v – u / a
Then, t = 40 – 20 / 10
t = 20 / 10
t = 2
Therefore, the time is 2 s.
