133 Two uniform spheres shown in figure rotate separately on parallel axis The upper sphere has angular speed wo and lower sphere is at rest Now the two spheres are moved together so that their surfaces touch After a short time the two spheres now in contact are rotating without slipping Find the final rate of rotation of upper sphere in rad s given moment of inertia of upper sphere I 4 kg m moment of inertia of lower sphere 1 2 kg m a 2 m b 1 m n 12 rad s R a R b
