potential energy at top = kinetic energy at bottom
m g h = (1/2) m v^2
h = v^2/(2g)
m g h = (1/2) m v^2
h = v^2/(2g)

max height is reached when it comes to a stop
v = 14-gt
solve for t when v=0 and use that to find h in
h = 14t - g/2 t^2
Or, use (or derive) a simpler more direct formula without finding t first.
