Question

2- Camila corre com uma velocidade de 5m/s se uma. massa for de 30kg, qual a energia cinética? ​

Answer 1

$Ec = \frac{m.V^{2} }{2}\\\\Ec = \frac{30.(5)^2}{2}\\ \\Ec = \frac{30.25}{2}\\\\Ec = \frac{750}{2} \\\\Ec = 375 J$

Answer 2

$\large\displaystyle\sf E_c=\dfrac{m\cdot v^2}{2}$

$\large\displaystyle\sf E_c=\dfrac{30\cdot5^2}{2}$

$\large\displaystyle\sf E_c=\dfrac{30\cdot25}{2}$

$\large\displaystyle\sf E_c=\dfrac{750}{2}$

$\large\displaystyle\text{ \boxed{\boxed{\sf E_c=375\,J}} }$
