The figure shows a communications satellite that is a solid cylinder with mass 1430 kg, diameter 1.24 m, and length 1.64 m. Prior to launch from the shuttle cargo bay, the satellite is set spinning at 1.37 rev/s about its long axis. What are (a) its rotational inertia about the rotation axis and (b) its rotational kinetic energy?

A solid cylinder has a moment of inertia of 0.08 kg- m^2. A torque of 5.0 N-m is applied to the disk so it begins to spin on an axis going through its center( assume the disk was originally at rest). what is the angular acceleration of the disk? What is the rotational kinetic energy of the disk after 2 seconds?
