what is the formula for max height? i remember there being some type with i think time and/or acceleration in the equation when you don't have a velocity

y=5(tsq)

vf=v0+at
the peak time is v0/a

if you know time, you can figure out y=vot + 1/2 a t^2

what's that first one??

and what's peak time?

y is half g t(sq) for freefall.

oh right thanks!!

When using h=1/2gt^2, you must remember that it's only good for voy=0.
