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

Answer: (C)

$y = 3x$

Answer 2

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. $\frac{x}{y} = \frac{1}{3}$ ⇒ $y = 3x$
