Estimate the skaters moment of inertia

Reference no: EM13501524

A reasonable estimate of the moment of inertia of an ice skater spinning with her arms at her sides can be made by modeling most of her body as a uniform cylinder. Suppose the skater has a mass of 64 kg. One eighth of that mass is in her arms, which are 60 cm long and 20 cm from the vertical axis about which she rotates. The rest of her mass is approximately in the form of a 20 cm-radius cylinder. Estimate the skater's moment of inertia to two significant figures.
