When some stars use up their fuel they undergo  a catastropic explosion is called a supernova.  The system blows much of the stars mass in th eform of a rapidly expanding spherical shell.  AS a siple model of the supernova process assume that the star is a solid sphere that is initially rotating at 1.9 revolutions per day

After the star explodes find the angular momentum in revolutions per day of the expanding supernova shell when the radius of the shell is 5.0 R.  Assume the stars mass is contained in that shell

**Chapter 09, Problem 60** When some stars use up their fuel, they undergo a catastrophic explosion called a supernova. This explosion blows much or all of a star's matter into space. As a simple model of the supernova process, assume that the star is a solid sphere of radius R that is initially rotating at 1.9 revolutions per day. After the supernova explosion, the star's matter expands into a thin spherical shell. Assume that all of the star's original mass is contained in that shell. Find the angular velocity, in revolutions per day, of the expanding supernova shell when its radius is 5.0R. **Diagram Explanation:** - The diagram consists of two images: 1. **Before:** A solid sphere labeled with an angular velocity of 1.9 revolutions per day. 2. **After:** An expanding spherical shell with a significantly larger radius, labeled with angular velocity ω (to be calculated). This problem involves concepts of rotational motion and conservation of angular momentum.
