Please refer to the picture to help answer the questions. A ice skater goes into a spin standing vertically with his arms outstretched horizontally. We can crudely model his torso and legs as a cylinder with radius 0.1m and mass 52 kg and each arm is a rod with mass 4 kg and length 0.9 m. The skater will initially spin at 2.0 rad/s. Question 1: what is the moment of inertia of the skater's torso and legs. Please answer in kg m^2. Question 2: What is

A ice skater goes into a spin standing vertically with his arms outstretched horizontally. We can crudely model his torso and legs as a cylinder with radius 0.1m and mass 52 kg and each arm is a rod with mass 4 kg and length 0.9 m. The skater will initially spin at 2.0 rad/s.
Question 1: what is the moment of inertia of the skater's torso and legs. Please answer in kg m^2.
Question 2: What is the moment of inertia of one of the skater's arms? Please answer in kg m^2.
Question 3: What is the total moment of inertia of the skater? Please answer in kg m^2

Can you please help me answer the last three parts of this same problem.
Question 4: What is the skater's
Question 5: The skater pulls his arms in to his chest and now he can be approximted as just a cylinder. What is his new moment of inertia? Please answer in kg m^2
Question 6: How fast is he spinning now that his arms are pulled in? Assume no external torque acts on him as he spins. Please answer in rad/s
