The ground state cooling of a mechanical oscillator in an optomechanical\ncavity containing an ensemble of identical two-level ground-state atoms is\nstudied in the highly unresolved-sideband regime. The system exhibits\nelectromagnetically-induced transparency-like quantum interference effect. The\nmutual interaction with the cavity optical field gives rise to an indirect\ncoupling between the atomic and mechanical modes. In presence of this\ninteraction, the noise spectrum gets modified and leads to asymmetric cooling\nand heating rates. Using the quantum master equation, time evolution of the\naverage phonon number is studied and it is observed that the average phonon\noccupancy in the mechanical resonator exhibits ground-state cooling.\n
