Consider five equal mass objects all with the same non-zero kinetic energy. Unless otherwise stated assume the axis of rotation is through the center-of-mass. Assume all densities are uniform or constant. Order these objects from lowest angular velocity (1) to highest angular velocity (5). Solid sphere of radius R. 4 Rod of length 2R (axis perpendicular to rod). 3 Solid disk of radius R (axis perpendicular to plane of disk). Rod of length 2R (axis perpendicular to rod, axis through END of rod). 1 2 Hoop of radius R (axis perpendicular to plane of disk). lext incorrect question <> > > > >
