Question

qual a energia cinetica de um automovel de massa 1700 kg que viaja a 30 m/s

Answer 1

m = 1700 kg

v = 30 m/s

Ec = J

Ec = m . v² / 2

Ec = 1700 . 30² / 2

Ec = 1700 . 900 / 2

Ec = 1530000 / 2

Ec = 765000 J

Answer 2

Boa tarde!


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

$Ec = \frac{1700 \times {30}^{2} }{2}$

$Ec = \frac{1700 \times 900| }{2}$

$Ec = \frac{1530000}{2}$

$Ec = 765 \: 000j$
