Suppose we want to calculate the moment of inertia of a 68. 5 kg skater, relative to a vertical axis through their center of mass.
A. First calculate the moment of inertia (in kg⋅m2) when the skater has their arms pulled inward by assuming they are cylinder of radius 0. 115 m. Ib = 0. 453 This was correct. I cannot figure part B
B. Now calculate the moment of inertia of the skater (in kg⋅m2) with their arms extended by assuming that each arm is 5% of the mass of their body. Assume the body is a cylinder of the same size, and the arms are 0. 875 m long rods extending straight out from the center of their body being rotated at the ends
