Determine from question #2 what k is and put into terms of g.

i got the answer for question 2 do we just use the answer for 2 and solve for g? because ive been doing that and its not working

k = (2h/g)^0.5 (answer for 2)
g = sqrt(k)/2h (wrong answer for 3)

can someone tell me what im doing wrong??

your algebra is incorrect.
k = (2h/g)^.5
square both sides=
k^2 = 2h/g
switch k and g=
g = 2h/k^2
