displacement?
А.
1st
B
2nd
С C
3rd
D
4th​

Answer 1

Answer:

The equation related to Initial velocity, final velocity , acceleration & displacement is 3rd equation .

$:\implies$ v² = u² + 2as

where,

• v denote final velocity
• u denote initial velocity
• a denote acceleration
• s denote displacement

So, the required option is 3rd !

Additional Information !!

Some other equation of motion are :-

• v = u + at

• s = ut + 1/2at²

Answer 2

Required Answer :-

Let

Initial velocity = u

Final velocity = v

Acceleration = a

Displacement = s

So,

$\sf (v^2)=u^2 + 2as$

$\sf v^2-u^2=2as$

Hence,

It is the third equation of motion

Know More :-

Acceleration is defined as the change in velocity with respect to time.

Displacement is defined as shorter distance required to cover the whole distance.

Initial velocity is defined as the velocity before the car starts accelerating.

Final velocity is defined as the last or final velocity when the object stops moving.
