Question

Qual a energia cinética de um caminhão de 25 kg á 108 km/h?​

Answer 1

$Dados:\\ V\longrightarrow 108 km/h \\m\longrightarrow 25kg \\\\\\\ Resposta:\\\\108\ Km/h \longrightarrow 30 m/s\\Ec=\frac{m.v^{2} }{2} \\\\Ec=\frac{25.30^{2} }{2} \\\\Ec=\frac{25.900}{2}\\\\Ec=\frac{22500}{2} \\\\\longrightarrow Resposta: Ec= 11250$
