$\sf{k=\dfrac{1}{\diagdown\!\!\!2}\cdot\diagdown\!\!\!\!\!\!10^5\cdot20^2}\\\sf{k=5\cdot400}\\\huge\boxed{\boxed{\boxed{\boxed{\sf{k=2000~J}}}}}$

Answer 2

$\Large{\begin{array}{l}\tt E_c=\dfrac{m\cdot v^2}{2}\\\ \\ \tt E_c=\dfrac{10\cdot20^2}{2} \\ \\\tt E_c=\dfrac{10\cdot400}{2} \\ \\\tt E_c=\dfrac{4000}{2} \\ \\\tt E_c=2000\,J\end{array}}$
