A dancer is spinning with his arms extended. In this position his rotational inertia is 1.6 kg m^2. During the spin, the dancer pulls the arms close to his body. In this position his rotational inertia is 1.0 kg m^2. Ignore friction with air or with the floor. If the dancers final angular velocity is 4.0 rev/min, what was his initial angular velocity with the arms extended? A. 0.4 rev/min B. None of the answers is correct C. 2.5 rev/min D. 1.2 rev/min E. 6.4 rev/min Show all work and steps: 1. Type the given information and assign a variable for each known value. 2. Type the general equations that you will use to solve the problem using variables (no numbers yet). 3. Type the given values with units to obtain the final
