Answer:
(i) Consider a body which
starts with initial velocity u and due to uniform acceleration a, its final
velocity becomes v after time t. Then, its average velocity is given by
Average velocity
The distance covered by the body in time t
is given by
Distance, s = Average velocity X Time
(ii) We know that
Also,
Þ
Putting the value of t in (1), we have
