Dos cajas conectadas por una cuerda de masa insignificante se encuentran en una superficie horizontal. La caja A tiene masa m, y la caja B tiene masa mg. El coeficiente de fricción cinética entre cada caja y la superficie es µk. Las cajas son empujadas hacia la derecha a una velocidad constante de 3.20 cm / s por una fuerza horizontal F. En términos de m, mg yu, calcule (a) la magnitud de la fuerza F y (b) la tensión en la cuerda que conecta los bloques. Incluya los diagramas de diagrama de cuerpo libre que utilizó para determinar cada respuesta.
