Q. A body starts from rest and moves with uniform acceleration. Which of the following graphs represent its motion
A) [image:3_image92.emf]
B) [image:3_image93.emf]
C) [image:3_image94.emf]
D) [image:3_image95.emf]
Explanation
(b) $v = u + at$ As $u = 0,\ v = at$
The graph (b) is correct as $v = 0$ at $t = 0$, and in the straight line graph $y = mx,\ y = v,\ m = a$ and $t = x$
