Question

(II) Suppose our Sun eventually collapses into a white dwarf,
losing about half its mass in the process, and winding up
with a radius 1.0% of its existing radius. Assuming the lost
mass carries away no angular momentum, (a) what would the
Sun’s new rotation rate be? Take the Sun’s current period to
be about 30 days. (b) What would be its final kinetic energy
in terms of its initial kinetic energy of today?
