Solved: Suppose our Sun eventually collapses into a white
Chapter 8, Problem 63(choose chapter or problem)
Suppose our Sun eventually collapses into a white dwarf, losing about half its mass in the process, and winding up with a radius 0% of its existing radius. Assuming the lost mass carries away no angular momentum, what would the Suns new rotation rate be? (Take the Suns current period to be about 30 days.) What would be its final ke in terms of its initial ke of today?
