A rod of mass M and length Z can rotate about a hinge at its left end and is initially at rest. A putty ball of mass m, moving with speed V. strikes the rod at angle 0 from the normal and sticks to the rod after the collision. What is the total moment of inertia, 7, with respect to the hinge, of the rod-ball-system after the collision? What is the angular speed of of the system immediately after the collision, in terms of system parameters and 7?
