Considere un bloque de masa M colocado sobre un mesa, la cual tiene coeficiente de roce estático μ. El bloque se encuentra atado, por medio de una cuerda de largo L, a una bola de masa m. Inicialmente ambos cuerpos se encuentran a la misma altura y la bola a una distancia d de la polea A. Como muestra la figura. En cierto instante se suelta la bola y esta cae describiendo una trayectoria circular, hasta que la cuerda forma un angulo θ con la horizontal. De la situación antes mencionada obtenemos el siguiente DCL para la bola de masa m.   determine cual son las ecuaciones de movimiento asociadas a la bola.
