I earlier asked a question about physics (as Mr. Squirrel). I was given a brilliant answer in a formula as my answer.
1/2t^2+i*t+h=c
t=time passed
i=initial velocity
h=initial height
c=current height
I plugged in a few things, trying to find "t".
t=?
i=0 (falling, so 0)
h=10m
c=5m
And the answer I got was:
t^2 = -10
THAT'S IMPOSSIBLE!
What's wrong with the formula, because I checked the math w/ my teacher, my dad, etc. So it isn't me.
Any ideas?
