Um bloco de massa 3,0 kg é abandonado com velocidade inicial nula no ponto A de um plano inclinado com atrito, como mostra a figura. O bloco atinge o ponto B com uma velocidade de 10 m/s. Supondo que a força de atrito exercida pelo plano inclinado sobre o bloco tenha sido constante e que , calcule: a) o módulo da aceleração do bloco durante a descida;
b) o módulo da força de atrito exercida sobre o bloco;
c) o módulo da força exercida pelo plano inclinado sobre o bloco.
