Question

Um móvel de massa de 10 kg registra uma velocidade de 10 m/s qual energia cinética deste móvel

Answer 1

$\Large\displaystyle\begin{gathered} \tt E_C=\frac{m\cdot v^2}{2}\end{gathered}$

$\Large\displaystyle\begin{gathered} \tt E_C=\frac{10\cdot10^2}{2}\end{gathered}$

$\Large\displaystyle\begin{gathered} \tt E_C=\dfrac{10\cdot100}{2}\end{gathered}$

$\Large\displaystyle\begin{gathered} \tt E_C=\frac{1000}{2}\end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\tt E_C=500\,J}}\end{gathered} }$
