have the correct answers listed below.. please show the work for how to get those answers! Figure 1025 The disk hits the stick at one end and adheres to it, and they rotate together, pivoting around the nail Angular momentum is conserved for this inelastic collision because the surface is frictionless and the unbalanced external force at the nal exerts no torque Suppose the disk in Figure 10:26 has a mass...
