A person with mass mp 76 kg stands on a spinning platform disk with a radius of R= 2.04 m and mass md=193 kg. The disk is initially spinning at w 1.8 rad/s. The person then walks 2/3 of the way toward the center of the disk (ending 0.68 m from the center).
4) What is the change in the total kinetic energy of the person and disk? (A positive value means the energy increased.) Submit You currently have 4 submissions for this question.
