Answer 1

Answer:

Hope you get the correct answer.

Answer 2

Answer:

First of all, you have to know the other two equations of motions :

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
