76. *** In Figure 8-47, two pulleys are mounted on fixed axles that have negligible friction. The small pulley has a moment of inertia of 9.0 kgm:; it is made up of two cylinders welded together, one of radius 7.0cm and the other of radius 15.0cm. The large pulley has a radius of 41 0cm and a moment of inertia of 84 kgms; the pulleys are coupled using a light belt. A 7.00kg mass hangs from the smaller pulley by a rope that is wound around the smaller cylinder. The system is initially at rest. Then the mass is let go and starts to fall. Figure 8-47 Problem 76 (a) Find the acceleration of the mass. (b) Find the tension in the rope
