Question

When some stars use up their fuel they undergo a catastrophic explosion called a supernova This explosion blows much or all of the star s mass outward in the form of a rapidly expanding spherical shell As a simple model of the supernova process assume that the star is a solid sphere of radius R that is initially rotating at 2 0 revolutions per day After the star explodes find the angular velocity in revolutions per day of the expanding supernova shell when its radius is 4 0R Assume that all of the star s original mass is contained in the shell rev day
