compute the new rotation period of the Sun.

Assume that the sun runs out of nuclear fuel and suddenly collapses to form a white dwarf star, with a diameter equal to that of the Earth. Assume no mass loss, what would then be the sun's new rotation period (time for one revolution), which currently is about 25 days? Assume that the sun and the white dwarf are uniform, solid spheres [I = (2/5)MR2]. MS = 2•1030 kg, RS = 6.96•108 m , RE = 6.37•106 m.
