Chapter 11, Problem 11.16(choose chapter or problem)
Suppose our Sun eventually collapses into a whitedwarf, losing about half its mass in the process, and windingup with a radius 1.0% of its existing radius. Assuming thelost mass carries away no angular momentum, what wouldthe Suns new rotation rate be? (Take the Suns currentperiod to be about 30 days.) What would be its final kineticenergy in terms of its initial kinetic energy of today?
