Question

Check the dimensional Correctness of the following results--
(a) Sn=u+1/2a(2n-1)
Where, Sn=Distance covered in nth second.
u=initial velocity of the body.
a=acceleration of the body.
n=time taken

Answer 1

I think Answer should be,

Answer: Sn=u+1/2a(n^2)

plz check the answer,

if it is right then Follow me... thankyou

Answer 2

just check dimensions of every single term and then equate them.IF they are all equal then they shall be dimensionally correct
