your equation is wrong

Md2004: V²-u²=2as can be written down as v²=u²+2asby transposing u² to lhs

Explanation:

$\huge\boxed {\pink {\mathbb{\underline {Answer}}}}$

From the 1st equation of motion...

$V=U+at\\</p><p>V-U=at\\</p><p>\frac{V-U}{a}=t\\</p><p>t=\frac {(V-U}{a)}$

Put the value in the 2nd equation of motion..

$S=\frac {1}{2}(V+U)\frac{V-U}{a}\\</p><p>S=\frac {1}{2a}(V^2-U^2)\\</p><p>2aS=V^2-U^2\\</p><p>\implies V^2-U^2=2aS</p><p>$
