s(t) = (1/2)at²+v_0*t
since the Maximum height is where the Velocity is 0 we can say:
t = (20m/s) / (9.81m/s²) = 2.03s
with our starting velocity of 20m/s we get ~21m of total height.
Since Energy cant be destroyed Not created it will have half its kinetic Energy when its Potential Energy is at half of max (which would be at Said 21m)
so its 10.5m

It depends on initial speed
