Finding distance -- Find the height of an object given ratio of two distances

[QUOTE="DEvens, post: 4991723, member: 475460"] The problem statement looks incomplete. What is n? Is n the number of seconds required to fall the distance H? Ok, you need to check your algebra a bit. (n-3)^2 is not (n^2 - 9). And 5 (n^2-9) is not 5n^2 + 45. And what are (I) and (II) and why should they be equal? Also, you need to be using the ratio you have been given. The distance in n-3 seconds is 4/3 the distance in the (n-3)rd second. [/QUOTE]
