Question

A body starting from rest moves along a straight line with a constant acceleration. The variation of speed (v) with distance (*) is represented by the graph

Answer 1

Correct option (c)

Explanation :

For linear motion of a body, v2 = u2 + 2as Initial velocity u = 0

.'. v2 = 2as where 'a' is constant.

It is an equation of a parabola. The curve is symmetrical to displacement axis. Hence curve (c) represents the motion.
