Question

A particle starting from rest travels a distance x in first 2 seconds and a distance y in next two seconds, then

• A. $y=x$
• B. $y=2x$
• C. $y=3x$
• D. $y=4x$

Answer 1

The correct option is C $y=3x$

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
$1:3:5:7....(2n-1)$
i.e. ratio of x and y will be $1:3$ i.e $\frac{x}{y}=\frac{1}{3}\Rightarrow y=3x$
