m FTI FT2 See the right Figure. The masses of the two objects are m and m2 respectively. The moment of inertia of the pulley is I and its radius is r. (a) If the coefficient of friction between object m2 and the tabletop is u, determine the acceleration a of the system and the tensions Fr and Fr2 in the rope, assuming there is no relative sliding between the rope and the pulley. (b) If object m2 is in smooth contact with the tabletop, calculate the acceleration a of the system and the tensions Fr and FT2 in the rope.
