A flying disk (180 g, 30.0 cm in diameter) spins at a rate of 340 rpm with its center balanced on a fingertip. 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 30.0-cm in diameter) and the remaining 30% is a nearly flat disk 30.0-cm in diameter? 1) What is the rotational kinetic energy of the Frisbee

In the figure the lower disk, of mass 440 g and radius 3.7 cm , is rotating at 180 rpm on a frictionless shaft of negligible radius. The upper disk, of mass 280 g and radius 2.0 cm , is initially not rotating. It drops freely down onto the lower disk, and frictional forces bring the two disks to a common rotational speed. A) Find the common speed. B) Find the fraction of the initial kinetic energy lost to friction.

A vinyl record that is 12 inches in diameter spins at a constant frequency of 33 1/3 rpm. It can be modeled as a solid disk with mass 225g. For the purpose of this problem we will assume there's no torque on the record; no friction to slow it down or motor to speed it up. 1) What is the angular momentum of the record? What is its kinetic energy? You place a nickel weighing 5.0 g on the very...
