Two balls of mass 3.29 kg are attached to the ends of a
thin rod of negligible mass and length 72 cm. The rod is
free to rotate without friction about a horizontal axis through its
center. A putty wad of mass 127 g drops onto one of the
balls, with a speed 2.5 m/s, and sticks to it.
What is the angular speed of the system just after the putty wad
hits?
1.31×10-1 rad/s
