Ummmmmmmmm do you have an answer key by chance? I came up with an answer, but I'm not very confident that it's correct :p hmm

OpenStudy (anonymous):

only if i get it wrong lol

zepdrix (zepdrix):

o :p

zepdrix (zepdrix):

do you get multiple guesses?

OpenStudy (anonymous):

3

zepdrix (zepdrix):

Hmmm should we burn one of those guesses on my attempt? :o If it's correct I can explain the process to you.

OpenStudy (anonymous):

uhh maybe wait a litte. ill let you know though

zepdrix (zepdrix):

Well anyway I came up with 265. Maybe someone else can confirm or reject that before you burn a guess :D

zepdrix (zepdrix):

Hmm ya I don't think that's right -_- thinkingggg

OpenStudy (anonymous):

lol its ok

OpenStudy (superdavesuper):

s=1/2*g*t^2 in this case, g is fixed at 400'...for t to be halved, g must be increased by 4x

OpenStudy (superdavesuper):

ooops typo....in this case, s is fixed at 400'....sorry!

OpenStudy (anonymous):

400 was incorrect

OpenStudy (superdavesuper):

so for t to be halved, g must be increased by 4x :)

OpenStudy (anonymous):

1600?

OpenStudy (superdavesuper):

Original g is 32....so 4x g would be...

OpenStudy (anonymous):

128?

OpenStudy (superdavesuper):
