Question : A body starts from rest, with uniform acceleration. If its velocity after 𝑛 seconds is 𝑣,then its displacement in the last two seconds is

(A) $\dfrac{2v\left( n+1\right) }{n}$

(B) $\dfrac{v\left( n+1\right) }{n}$

(D) $\dfrac{2v\left( n-1\right) }{n}$

Answer : option (D)

Solution :

A body starts from rest, with uniform acceleration. If its velocity after 𝑛 seconds is 𝑣,then its displacement in the last two seconds is
