Suppose we want to calculate the
moment of inertia of a 67 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.
Part
(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...
