Personondisk a person with mass mp = 76 kg stands on a spinning platform disk with a radius of r = 1.86 m and mass md = 190 kg. the disk is initially spinning at ω = 1.6 rad/s. the person then walks 2/3 of the way toward the center of the disk (ending 0.62 m from the center). 1)what is the total moment of inertia of the system about the center of the disk when the person stands on the rim of the disk? kg-m2 2)what is the total moment of inertia of the system about the center of the disk when the person stands at the final location 2/3 of the way toward the center of the disk? kg-m2
