Find the new rotation period of the star

Reference no: EM13520816

A star with the same mass and diameter as the sun rotates around a central axis with a period of 28.8 days. Suppose that the sun runs out of fuel and collapse to form a white dwarf star with a diameter to that of the earth. Assume th star acts like a solid sphere and that there is no loss of mass in the process.

Radius of Sun=6.96E8

Radius of Earth= 6.37E6

A.) What would be the new rotation period of the star (sec)?

B.) What is the ratio of final to initial kinetic energies?
