can anyone help me with this....

make t the subject $\displaystyle s = 1/2at^2$

i dont know how to start it, dont want to end up with fraction of fractions

$\displaystyle s = 1/2at^2$ divide by 1/2 to get

$\displaystyle 2s = at^2$ tthen divide by a to get

$\displaystyle 2s/a = t^2$ then square root to get

$\displaystyle t= \sqrt{ 2 s/a}$

sorry im no good at usign this [tex] stuff

$\displaystyle \sqrt{\frac{2s}{a}}=t$
