I'm from over the PHF site, i was wondering if you masters of maths could help me or just say no that's it thats the equation to use?
Obviously by now i realise the asker should post their attempt, so i will, but what i'm asking is for an alternative solution.
A stone is dropped from a cliff in the last 2 secs it travels a decimal fraction of 0.5665 of the total height, find the total time?
This is my attempt of which i know will be correct, sorry but i haven't mastered laTEX as of yet!
2/(1-sq-rt(1-0.5665)) = 5.855 secs
I know how to click the thanks button too!
