Question

calcule a energia cinetica de um carro de 1500 kg, que se move a velocidade de 10 m/s

Answer 1

Basta usar a equação da energia cinética:
$E_c=\frac{m*v^2}{2}$
$E_c=\frac{1.500*10^2}{2}$
$E_c=\frac{1.500*100}{2}$
$E_c=75.000\ J$

Answer 2

$\Large\displaystyle\text{ \begin{gathered}\hookrightarrow \boxed{\boxed{\bf E_C=75000~J}}\end{gathered} }$

• Explicação:

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

$\Large\displaystyle\begin{gathered} \sf E_C=\dfrac{1500\cdot 10^2}{2}\end{gathered}$

$\Large\displaystyle\begin{gathered} \sf E_C=\dfrac{1500\cdot 100}{2}\end{gathered}$

$\Large\displaystyle\begin{gathered} \sf E_C=\dfrac{150000}{2}\end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\sf E_C=75000~J}}\end{gathered} }$
