We know that acceleration is defined as the rate of change of velocity = so a= v-u/t
v-u = at
v = at + u
We know that average velocity = v+u/2 = s/t
So (v+u)t/2 = s
( u + at + u )t/2= s
(2u + at ) t /2 = s
2ut + at^2 /2 = s
ut + 1/2at^2 = s
v-u = at
v = at + u
We know that average velocity = v+u/2 = s/t
So (v+u)t/2 = s
( u + at + u )t/2= s
(2u + at ) t /2 = s
2ut + at^2 /2 = s
ut + 1/2at^2 = s
