Motion in a Straight Line

A small block slides down on a smooth inclined plane, starting from rest at time t=0t = 0. Let SnS_n be the distance travelled by the block in the interval t=n−1t = n - 1 to t=nt = n. Then the ratio SnSn+1\dfrac{S_n}{S_{n+1}} is:

  1. A.2n−12n\dfrac{2n-1}{2n}
  2. B.2n−12n+1\dfrac{2n-1}{2n+1}✓
  3. C.2n+12n−1\dfrac{2n+1}{2n-1}
  4. D.2n2n−1\dfrac{2n}{2n-1}

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
