Q. A phonograph record of radius 6 cm and mass 15 g is rotating with an angular velocity of 33.3rev/min. A penny of mass 1.00g suddenly falls on the record and lands at a radial distance of 4 cm from the records center. What is the angular velocity after collision?

Q. A uniform spherical shell of mass 8.60kg with diameter 48 cm has four small masses of mass 2.00kg attached to its outer surface and equally spaced around it. This combination is spinning about an axis running through the center of the sphere and two of the small masses.
