Sobre un plano inclinado que forma 37° con la horizontal, se encuentra un bloque A, de masa 6 , unido por medio
de una cuerda a otro bloque B, de masa 3 que cuelga de la cuerda, la cual pasa por una polea situada en la parte
inferior del plano. Si el coeficiente de rozamiento entre el bloque y el plano es = 0.4, calcular la aceleración del
sistema y la tensión del hilo.
