A car starts from rest and moves with constant acceleration. The ratio of distance covered by the car in nth second with that covered in n seconds is:

Options

A. `(2n-1)/(2n^(2))`
B. `(n^(2))/(2n-1)`
C. `(2n-1)/(n^(2))`
D. 1:n

Answer

c

Explanation

Here `(S_n)/(s)=((a)/(2)(2n-1))/((1)/(2)an^(2))=(2n-1)/(n^(2))`
