The image above represents final velocity.

To compute for final velocity, three essential parameters are needed and these parameters are **initial velocity (u), acceleration (a) **and **distance covered (S).**

The formula for calculating final velocity:

v = √(u² + 2as)

Where;

v = Final Velocity

u = Initial Velocity

a = Acceleration

s = Distance Covered

Let’s solve an example;

Find the final velocity when the initial velocity is 13, acceleration is 9.8 and the distance covered is 32.

This implies that;

u = Initial Velocity = 13

a = Acceleration = 9.8

s = Distance Covered = 32

v = √(u² + 2as)

v = √(13² + (2 x 9.8 x 32))

v = √(169 + (627.2))

v = √(796.2)

v = 28.21

Therefore, the **final velocity **is **28.21 m/s.**

**Calculating the Initial Velocity when the Final Velocity, the Acceleration and the Distance Covered is Given.**

u = √v² – 2as

Where;

u = Initial Velocity

v = Final Velocity

a = Acceleration

s = Distance Covered

Let’s solve an example;

Find the initial velocity when the final velocity is 30, the acceleration is 8 and the distance covered is 11.

This implies that;

v = Final Velocity = 30

a = Acceleration = 8

s = Distance Covered = 11

u = √v² – 2as

u = √30² – 2(8 x 11)

u = √900 – 2(88)

u = √900 – 176

u = √724

u = 26.90

Therefore, the **initial velocity **is **26.90 m/s.**

**Calculating the Acceleration when the Final Velocity, the Initial Velocity and the Distance Covered is Given.**

a = ^{v2 – u2} / _{2s}

Where;

a = Acceleration

v = Final Velocity

u = Initial Velocity

s = Distance Covered

Let’s solve an example;

Find the acceleration when the final velocity is 10, initial velocity is 8 and the distance covered is 7.

This implies that;

v = Final Velocity = 10

u = Initial Velocity = 8

s = Distance Covered = 7

a = ^{v2 – u2} / _{2s}

a = ^{102 – 82} / _{2(7)}

a = ^{100 – 64} / _{14}

a = ^{36} / _{14}

a = 2.57

Therefore, the **acceleration **is **2.57.**

**Calculating the Distance Covered when the Final Velocity, Initial Velocity and Acceleration is Given.**

s = ^{v2 – u2} / _{2a}

Where;

s = Distance Covered

v = Final Velocity

u = Initial Velocity

a = Acceleration

Let’s solve an example;

Given that the final velocity is 20 and the acceleration is 10 and the initial velocity is 14. Find the distance covered?

This implies that;

v = Final Velocity = 20

u = Initial Velocity = 14

a = Acceleration = 10

s = ^{v2 – u2} / _{2a}

s = ^{202 – 142} / _{2(10)}

s = ^{400 – 196} / _{20}

s = ^{204} / _{20}

s = 10.2

Therefore, the **distance covered **is **10.2 m.**
