Problem 3: Suppose we want to calculate the moment of inertia of a 65.5 kg skater, relative to a vertical axis through their center of mass. Part (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 0.11 m. 4 = 0.3962 / Correct! Part (b) Now calculate the moment of inertia of the skater (in kg m-) 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 0.825 m long rods extending straight out from the center of their body being rotated at the ends.
