A star rotates with a period of 30 days about an axis through its center. The period is the time interval required for a point on the star's equator to make one complete revolution around the axis of rotation. After the star undergoes a supernova explosion, the stellar core, which had a radius of 1.0 x 104 km, collapses into a neutron star of radius 3.0 km. Determine the period of rotation of the neutron star.
Suppose that Earth's polar ice caps melted and the water returned to the oceans, so that the oceans were deeper by about 15.1 m. What effect would this have on Earth's rotation? Make an estimate of the resulting change in the length of the day. (Concern has been expressed that warming of the atmosphere resulting from industrial pollution could cause the ice caps to melt.)
In Star Trek: The Next Generation, a Borg
Cube is a cubical structure of 3.036 km on a side and total mass of 9.0 × 1010
kg, (with a volume of 27 cubic kilometers).
a) The Borg Cube is slowly rotating to face away from the Federation
Fleet. If it takes 20 seconds to turn through one-quarter of a revolution,
what's its average angular speed, in radians per second?
b) If the Borg Cube stops rotating (comes to a full stop) in a time of
exactly one minute, what is its average angular acceleration, in radians per
second2?
c) What is the rotational kinetic energy of the Borg Cube if it is rotating
at the angular speed of 0.07854 radians per second? {Note: for the moment
of inertia of the Borg Cube, use the equation for a slab, rotating about an
axis thru its center

- Why is the following situation impossible? A space station shaped like a giant wheel has a radius of r = 100 m and a moment of inertia of 5.00 108 kg m2. A crew of 150 people of average mass 65.0 kg is living on the rim, and the stations rotation causes the crew to experience an apparent free-fall acceleration of g (Fig. P10.52).
