The uniform rod (length 0.60 m, mass 1.0 kg) in Fig. 10-85 rotates in the plane of the figure about an axis through one end, with a rotational inertia of `0.12kg*m^(2)`. As the rod swings through its lowest position, it collides with a 0.20 kg putty wad that sticks to the end of the rod. If the rod's angular speed just before collision is 2.4 rad/s, what is the angular speed of the rod-putty system immediately after collision?
