Question

Am I right?

Answer 1

I think its C.

Answer 2

Nope. That's not right.

Answer 3

Take it in this way :

\(s = u + 0.5 t^2 \\
s - u = 0.5 t^2\)

Right?

Answer 4

Now divide \(\color{blue}{0.5}\) both sides.

\(\cfrac{s-u}{\color{blue}{0.5}} = \cfrac{0.5t^2}{\color{blue}{0.5}} \)

\(\cfrac{s - u}{0.5} = \cfrac{\cancel{0.5} t^2}{\cancel{0.5} } \)

\(\cfrac{s-u}{0.5} = t^2\)

Square root both sides and you're done.

Answer 5

So A?
