Average velocity = (Initial velocity + final velocity)/2
OR
Vav = (u + Vf)/2
but Vf = u + atPutting the value of Vf
Vav = (u+ u+ at)/2
Vav = (2u+ at)/2
Vav = 2u/2 + at/2
Vav = u + at/2
Vav = u + 1/2at.......................................(i)
we know that
S = Vav * t
Putting the value of ‘Vav’
S = [u + 1/2at] t
S= ut + 1/2at*t
