Two 3.00 kg balls are attached to the ends of a thin rod of
negligible mass, 50.0 cm long. The rod is free to rotate in a
vertical plane without friction about a horizontal axis through its
center. While the rod is horizontal (Fig. 12-46), a 65.0 g putty
wad drops onto one of the balls with a speed of 3.00 m/s and sticks
to it.(a) What is the angular speed of the system just after the putty
wad hits?(b)...
