Question

drive equation (a) v²-u²=2as (b) v=u+at

​

Answer 1

Answer:

l think so (b)

pls mark as brainliest if it's right

Answer 2

Answer:

K check the explanation

Explanation:

(b)V=u+at  

(a)  1.V=u+at  

     2.S=ut+1\2at2  

Now the derivation:

From the first equation we have :

at=v−u  

t=v−u\a  

Now putting the value of t in the second equation of motion:

s=u(v−u\a)+1\2a(v−u\a)2  

s=uv−u2\a+a(v2+u2–2vu)\2a2  

s=uv−u2\a+(v2+u2+2vu)\2a  

s=(2uv−2u2+v2+u2–2vu)\2a  

2as=v2−u2  

v2=u2+2as

Hope this helps u clearing ur doubt. All the best!!
