A solid sphere of radius 2.69 cm and a spherical shell of radius 6.87 cm are rolling without slipping along the same floor. The two objects have the same mass. If they are to have the same total kinetic energy, what should the ratio of the sphere's angular speed wsph to the spherical shell's angular speed Wshl be?
