Answer:
[tex]\large \boxed{\sf t=\sqrt{\frac{2s}{a}} }[/tex]
Step-by-step explanation:
[tex]\displaystyle s=\frac{at^2}{2}[/tex]
Multiply both sides by 2
[tex]2s=at^2[/tex]
Divide both sides by a
[tex]\displaystyle \frac{2s}{a} =t^2[/tex]
Take the square root of both sides
[tex]\displaystyle \sqrt{\frac{2s}{a}} =t[/tex]
