Figure 11-43 shows two blocks, each of mass m, suspended from the ends of a rigid weightless rod of length L1+L2 with L1 = 19 cm and L2 = 82 cm. The rod is held horizontally on the fulcrum and then released. (a) What is the magnitude of the initial acceleration of the block closer to the fulcrum. ______ m/s2(b) What is the magnitude of the initial acceleration of the other block? ______ m/s2
