A flying disk (160 g, 25.0 cm in diameter) spins at a rate of 300 rpm with its center balanced on a fingertip.
(A) What is the rotational kinetic energy of the Frisbee if the disc has 70% of its mass on the outer edge (basically a thin ring 25.0-cm in diameter) and the remaining 30% is a nearly flat disk 25.0-cm in diameter?
(B) What is the rotational kinetic energy of the Frisbee? (Express your answer to two significant figures.)
