A potter's wheel is rotating arounda vertical axis through its center at a frequency of 1.8 rev/s. The wheel can be considered a uniformdisk of mass 6.0 kg and diameter 0.40m. The potter then throws a 3.1 kg chunk of clay, approximatelyshaped as a flat disk of radius 8.0 cm, onto the center of therotating wheel. What is the frequency of the wheel after the claysticks to it?
