Constants| Periodic Table Part A In the figure the lower disk, of mass 430 g and radius 3.1 cm, is rotating at 180 rpm on a frictionless shaft of negligible radius. The upper disk, of mass 270 g and radius 2.5 cm, is initially not rotating. It drops freely down onto the lower disk, and frictional forces bring the two disks to a common rotational speed. (Figure 1) Find the final common frequency in rpm. Express your answer using two...
