An object of mass m is attached to a horizontal spring, stretched to a displacement A from equilibrium and released, undergoing harmonic oscillations on a frictionless surface. The experiment is then repeated with a mass of 4m. Compared to the original total mechanical energy, the subsequent total mechanical energy of the object with mass 4m is
1.greater.
2.less.
3.equal.
