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

Answer:

[tex]\sqrt{\frac{2h}{g}[/tex]

Step-by-step explanation:

h=1/2gt^2

x 2

2h=gt^2

/g

2h/g=t^2

then square root
