concept of energy instead. Try another version > A descio.org Example 2 Two masses A and B are connected by a rope that is on top of a pulley (see figure). Block A has a mass of mA = 6.5 kg and block B has a mass of mp 20 kg. The pulley has a mass of Mp = 6.3 kg and can rotate without friction on its axis. Treat the pulley as a homogeneous disk of radius Rp = 0.7 m. Initially, block A is resting on the ground while block B is hanging H = 11 m above the ground. Because of the difference in mass, block B will accelerate down, while block A will move up. At time t = 0 the system starts to move and block A is lifted off the ground. In this problem use g = 9.8 m/s². MA MB answer= 2a) Determine the rotational inertia I of the pulley. units? C
