Cálculo de todas as forças e da aceleração
Não sei como iniciar o calculo para resolver esse problema,procurei respostas em vários lugares,mas não estou conseguindo realizar o cálculo
Uma locomotiva de 30000 kg é utilizada para movimentar dois vagões, um de combustível, de 5000 kg, e outro, com passageiros,de 25000 kg.
Sabe-se que a força de tração sobre a locomotiva é de 30000N
coeficiente de atrito=0,008
