Question

What is the formula for t in this equation : s=1/2at^2 .

Answer 1

s=1/2at^2
2s = at^2
t^2 = 2s/a
t = +  square root (2s/a) and t = -  square root (2s/a) 
or
       +  square root (2sa)
 t = ------------------------------
                a        
 and
        -  square root (2sa)
 t = ------------------------------ 
                a
