A body starts from rest and its distance...

A body starts from rest and its distance covered in n" second is given by `S_(n^(th)) =(a)/(2) (2n-1)` ,when 'a' is acceleration of the body. Then SI unit of `S_(n^(th))` is

A

m

B

`ms^(-1)`

C

`ms^(-2)`

D

`ms^(-3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`S_(nth)` represents distance per unit time and not distance.
