Suppose a star has a mass three times that of our sun (that is, the star's mass will be 6 x 1030 kg) and starts out as a sphere with an initial radius several times larger than our sun (3.48 x10º m). It is initially spinning with one revolution every 12 days. What is its angular momentum, in kg m2/s?

Consider a dual-propeller airplane circling above an airport. The radius of the airplane's path is 2000 meters and it completes one rotation every 10 minutes. The plane has a mass of 1750 kg and its propellers are spinning at 20b rad/s. The propellers consist of two blades each (approximately cylindrical), each with a mass of 5 kg and a length of 0.2 meters. What is the combined angular momentum of the propellers on the aircraft? 26.6 kg*m^2/s Submit Answer Incorrect. Tries 3/5 Previous Tries Ignoring the propellers, what is the angular momentum of the plane circling the airport? Submit Answer Tries 0/5

A merry-go-round of radius R = 2.6 m has a moment of inertia I = 223 kg × m2, and is rotating at 10 rpm. A child whose mass is 44 kg jumps onto the edge of the merry-go-round with a speed of 4.5 m/s in a direction tangential to the rim of the MGR, and in the direction in which it is spinning. The new angular speed (in rpm) of the merry-go-round is approximately

The end state of our sun will most likely be a white dwarf star. It would have about one fourth of its current mass and a radius about two percent of its current radius. The Sun today takes 30 days to rotate once about its internal spin axis. This is equivalent to an angular speed of 2.42 x 10-6 rad/s. Its moment of inertia today can be approximated as 3.86 x 1047 kg m². Its final angular speed will be 2.42 x 10-2 rad/s. What would its' final moment of inertia be? Select one: a. b. 1.52 x 10-55 kg m² OC. 6.59 x 1054 kg m² 3.86 x 1051 kg m² 3.86 x 1043 kg m² d.

A 1500-kg satellite orbits a planet in a circular orbit of radius 6.2 × 106 m. What is the angular momentum, in kg m2/s, of the satellite in its orbit around the planet if the satellite completes one orbit every 1.5 × 104 s?

Three children are riding on the edge of a merry-go-round that is a disk of mass 110 kg, radius 1.5 m, and is spinning at 18 rpm. The children have masses of 21.2 kg, 28.4 kg, and 33.8 kg.  If the child who has a mass of 28.4 kg moves to the center of the merry-go-round, what is the new magnitude of angular velocity in rpm?
