4. Consideremos um plano inclinado, onde o corpo de massa m, = 5Kg está ligado a um corpo de
massa m= 8Kg pendurado por um fio inextensível que passa através de uma roldana fixa de peso
desprezível. Sabendo que o coeficiente de atrito entre o plano e o corpo é 0,3 e o ângulo do plano é
30º. Considera g = 10m/s?, calcula:
a) A aceleração do sistema
b) A tensão no fio.
