Question 212171
s=1/3gt^2,,,,,,,,,we  think  it  should  be  1/2  gt^2,  but  we'll  do  the  problem  as  is,,,but  g  is  not  squared
.
multiply  by  3,,,,,and  divide  by  g
.
3s/g = t^2
.
take  square  root  both  sides
.
t - +/- sqrt(3s/g),,,,,,,,answer
.
.

if,  s=1/3(gt)^2,,,  then  just  mult  by  3
.
3s = (gt)^2
.
take  sq rt
.
gt = +/- sqrt(3s)
.
t= +/- [sqrt(3s)}/g
.
.
However,  we  still  like,,,,t= +/- sqrt(2s/g)
.
