Question: Two objects are connected by a massless string through an ideal pulley system as it is illustrated in the figure. The masses of the objects

Two objects are connected by a massless string through an ideal pulley system as it is illustrated in the figure. The masses of the objects are 1 and 2. The coefficients of static and kinetic friction between 1 and the flat surface are and , respectively, and the inclined surface is frictionless. a) Draw the force diagrams for both objects in this system. (10) b) Find the mass 2 which puts the system on the verge of sliding. Write the answer in terms of 1, 2, angle , and the coefficient of friction. (10) c) Now suppose that the system moves and slides down the incline; Find the acceleration of the system in terms of 1, 2, the angle , and coefficient of friction. (15)
