Expert Answer
Distance S travelled by a body that is moving with uniform acceleration is given as
Distance S = Average velocity × time
Let u is initial velocity , v is final velocity after time t .
Average velocity = ( u + v) /2
Final velocity v is given as , v = u + ( a × t )
where a is uniform acceleration
Hence average velocity = [ u + u + ( a × t ) ] /2 = u + [ (1/2) a × t ]
Distance S travelled int time t , S = { u + [ (1/2) a × t ] } × t = ( u t ) + [ (1/2) a t2 ]
