MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A satellite is spinning at 6.2 revy's. The satellite consists of a main body in the shape of a solid sphere of radius 3.0 m and mass 10,000 kg and two antennas project on the center of mass of the main body that can be approximated with rods of length 5.0 m each and mass 12 kg. The antennas lie in the plane of rotation. What is the angular momentum of the satellite about its center? (Enter the magnitude in kg . me/s.

The Crab Nebula Pulsar in the constellation Taurus has a period of 33.5 x 10-s, radius 10.0 kim, and mass 2.8 x 1030 kg. The pulsar's rotational period will increase over time due to the release of electromagnetic radiation, which doesn't change its radius but reduces its rotational energy. (Assume the pulsar is rotating in the counterclockwise direction. Indicate the direction with the signs of your answers.) (a] What is the angular mo ntum of the pulsar (in kg . m?/s)
