Question

A body starts from rest and. moves with acceleration a for time t.The average velocity over time t.

Answer 1

total displacement/ time

Answer 2

Hope u like my process
=====================
We know that.

$= > \bf \: v = u + at \\ \\ where \: \: v = final \: \: velocity \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: u = initial \: \: velocity \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: a = acceleration \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: t = time\: \:$

____________________
So

=> V = 0+ at = at


Average velocity
$= \frac{v + u}{2} = \frac{at}{2}$
