A man on flat ice, his arms outstretched, is rotating about the vertical axis with angular speed, ωi = 20 rad/s. He pulls the arms in towards the axis to reduce his rotational inertia from, Ii = 2.4 kg-m2 to, If = 1.6 kg-m2. What is his angular speed wf after pulling the arms towards the axis?

While placing a compact disc into a CD player, you notice a small chip on its edge. You attempt to play the CD anyway by placing the CD into the player's deck with the chip at 0o = 12.6° as measured from the +x-axis. The CD begins to rotate with angular acceleration a = 2.31 rad/s². If the CD has been spinning for t = 3.51 s and the disc has a radius of r = 6.00 cm, what are the x-y coordinates of the chip after this time, assuming the center of the disc is located at (0.00,0.00). X = y = cm cm
