Question

a body starts from rest and moves with a uniform acceleration the ratio of the distance covered in Nth second to the distance covered in n second​

Answer 1

distance covered in n second= 1/2an^2.

distance covered in nth second= 1/2 a(2n-1).

hence, required ratio=n^2:(2n-1).

Answer 2

Formula for distance in nth second, s = u + a(2n-1)/2

Hence S(nth Second) = 0 + a(2n-1)/2 = a(2n-1)/2

S (n second) = ut + at^2/2

                     = a(n)^2/2

                     = an^2/2

Hence, Ratio = 2n-1 : n^2
