Q.
A body starts from rest travels a distance $x$ in first two seconds and a distance $y$ in next two seconds. The relation between $x$ and $y$ is
Motion in a Straight Line
Solution:
If particle starts from rest and moves with constant acceleration then in successive equal interval of time the ratio of distance covered by it will be:
$
1: 2: 5: 7 \ldots \ldots(2 n-1)
$
i.e., ratio of $x$ and $y$ will $b 1: 3$ i.e., $\frac{x}{y}=\frac{1}{3} \Rightarrow y=3 x$
