Suppose our Sun eventually collapses into a white dwarf, in the
process losing about one third of its mass and winding up with a
radius 2.0 percent of its existing radius.
What would its new rotation rate be? (Take the Sun’s current
period to be about 30 days.)
__________ rad/s
What would be its final KE in terms of its initial KE of
today?
(KEfinal / KEinitial) =
