Question

A small block slides without friction down an iclined plane starting form rest. Let `S_(n)` be the distance traveled from time `t = n - 1` to `t = n`. Then `(S_(n))/(S_(n + 1))` is:
A. `(2n - 1)/(2n)`
B. `(2n + 1)/(2n - 1)`
C. `(2n - 1)/(2n + 1)`
D. `(2n)/(2n + 1)`

Answer 1

Correct Answer - C
`S_(n) = (a)/(2) (2n - 1) , S_(n + 1) = (a)/(2) (2n + 1)`
`(S_(n))/(S_(n + 1)) = (2n - 1)/(2n + 1)`
