Consider a particle of mass m = 24.0 kg revolving around an axis with angular speed . The perpendicular distance from the particle to the axis is r = 0.500 m. Assume = 29.0 rad/s. What is the magnitude v of the velocity of the particle in m/s? Find the moment of inertia. Find its kinetic energy K .

Unformatted text preview: without friction about an axle through its center. A 3.00 kg stone is tied to the free end of the string, as shown in the figure. When the system is released from rest, you determine that the stone reaches a speed of 3.50 m/s after having fallen 2.50 m. What is the mass of the cylinder?
