Question 215777
Solve for g then t:
{{{d = (1/2)gt^2}}} Multiply both sides by 2 to clear the fraction.
{{{2d = gt^2}}} Now divide both sides by {{{t^2}}}
{{{2d/t^2 = g}}} or {{{highlight(g = 2d/t^2)}}}
Solve for t:
{{{d = (1/2)gt^2}}} Multiply both sides by 2.
{{{2d = gt^2}}} Divide both sides by {{{g}}}
{{{2d/g = t^2}}} Finally, take the square root of both sides.
{{{sqrt(2d/g) = t}}} or {{{highlight(t = sqrt(2d/g))}}}
