Rank the cases shown below from slowest final angular speed to fastest final angular speed.
Here ""final"" refers to the angular speed when the demonstrator's arms are pulled in. If two cases have the same angular speed, place one on top of the other. 1. Initial angular speed 0.5 omega_0, mass 0.5 m 2. Initial angular speed 2 omega_0, mass 2m 3. Initial angular speed 0.5 omega_0, mass m 4. Initial angular speed omega_0, mass 2m 5. Initial angular omega_0, mass m 6. Initial angular speed 2 omega_0, mass m a. Slowest b. Fastest
