Question

guys plz answer this with explanation ​

Answer 1

ANSWER

BODY MOVES WITH CONSTANT ACCELERATION WE CAN APPLY KINAMATIC EQUATIONS

initial velocity u = 0

distance covered in nth second

S = u + 1/2 a(2n-1)

since u= 0

S = 1/2 a(2n-1)

also distance covered in n secondes

= ut+1/2 at^2= at^2 = 1/2 a n^2

so required ratio is

= 2n-1 / n^2

= 2n/n^2 - 1/n^2

= 2/n -1/n^2

hope it helps

follow me
