12.95. Model: Because no external torque acts on the star during gravitational collapse, its angular momentum is conserved. Model the star as a solid rotating sphere. Solve: (a) The equation for the conservation of angular momentum is 22 if i f ii ff i fi f 55 LL I I m R m R RR ω ωω ⎛⎞ =⇒ = ⇒ = ⎜⎟ ⎝⎠ ⇒= The angular velocity is inversely proportional to the period
