Q. If a body starts from rest, the time in which it covers a particular displacement with uniform acceleration is:
Motion in a Straight Line
A
inversely proportional to the square root of the displacement
14%
B
inversely proportional to the displacement
17%
C
directly proportional to the displacement
41%
D
directly proportional to the square root of the displacement
27%
Solution:
Using $s = ut + \frac{1}{2}at^2$ as initial velocity is zero hence.
$s = \frac{1}{2} at^2$
$\Rightarrow t \propto \sqrt{s}$
