v2=u2+2as​

Answer 1

Hey U R Answer

Explanation:

We will use both of the equations of motion to reach thehird equation of motion. This will require a bit of algebra. 

S=ut+21at2andv=u+at, include the time variant t

There will be some situations when we do not have any information about time and so it would be a good idea to derive an equation that does not have a t term. 

To do this, we rearrange our first equation to get  

t=av−u

and use this to replace t wherever it appears in the second equation. So 

S=ut+21at2 becomes,

S=u(av−u)+21a(av−u)2

⇒2aS=2u(v−u)+(v−u)2

⇒2aS=2uv−2u2−v2−2uv−u2

⇒2aS=v2−u2
