A frisbee is moving through the air with a constant angular velocity of 10 cycles/s and a constant center of mass velocity of 20 m/s. Which of the following statements is true. a. The frisbee is in translational equilibrium, but it is not in rotational equilibirum. b. The frisbee is not in translational equilibrium, and it is not in rotational equilibirum. C. The frisbee is not in rotational equilbrium. d. The frisbee is in total equilibrium. e. The frisbee is not in translational equilibrium.

A spherical shell with a mass of 1.43 kg and a radius of 0.39 m is rolling across the level ground with an initial angular velocity of 35.9 rad/s. It is slowing at an angular rate of 2.6 rad/s². What is its rotational kinetic energy after 4.7 s? The moment of inertia of a spherical shell is I = 글MR2

Moment of inertia is: O A. The point at which all forces appear to act. B. The rotational equivalent of mass. OC. The time at which the mechanical energy of rotation is minimum. O D. The time at which the kinetic energy is minimum.
