Question

qual a energia cinética de um carro com massa 600 kg que viaja a 10 m/s ?

Answer 1

$\mathsf{E_{c} = \frac{mv^{2}}{2}}$

$\mathsf{E_{c} = \frac{600 \times 10^{2}}{2}}$

$\mathsf{E_{c} = 300 \times 100}$

$\boxed{\boxed{\mathsf{E_{c} = 30.000J}}}$

Answer 2

Ec= m.v^2/2
Ec= 600.10^2/2
Ec= 600.100/2
Ec= 60000/2
Ec= 30000J
