JEE Advance - Physics (2004 - No. 4)
A particle starts sliding down a frictionless inclined plane. If Sn is the distance traveled by it from time t = n - 1 sec to t = n sec, the ratio Sn / Sn+1 is
$${{2n - 1} \over {2n + 1}}$$
$${{2n + 1} \over {2n}}$$
$${{2n} \over {2n + 1}}$$
$${{2n + 1} \over {2n - 1}}$$
