Question

Um corpo de massa 10kg se desloca com velocidade constante de 10 m/s.Calcule a energia cinética desse corpo.​

Answer 1

Ec = $\frac{m . v^{2} }{2}$

Ec = $\frac{10 . 10^{2} }{2}$

Ec = $\frac{10 . 100}{2}$

Ec = $\frac{1000}{2}$

Ec = 500 J

Answer 2

$\Large{\begin{array}{l}\tt E_c=\dfrac{m\cdot v^2}{2}\\\ \\ \tt E_c=\dfrac{10\cdot10^2}{2} \\ \\\tt E_c=\dfrac{10\cdot100}{2} \\ \\\tt E_c=\dfrac{1000}{2} \\ \\\tt E_c=500\,J\end{array}}$
