Answer:
sqrt(2h/g) = t
Step-by-step explanation:
h=1/2gt^2
We want to get t alone
First multiply by 2 to get rid of the fractions
2*h=2*1/2gt^2
2h = g t^2
Then divide by g on each side
2h/g = g t^2/g
2h/g = t^2
Then we need to take the square root of each side
sqrt(2h/g) = sqrt(t^2)
Normally we take the ± sqrt, but since time must be positive ( cannot have negative time)
sqrt(2h/g) = t
