The maximum energy a bone can absorb without breaking is surprisingly small. Experimental data show that a leg bone of a healthy, \(80\,\text{kg}\) human can absorb about \(240\,\text{J}\). From what maximum height could an \(80\,\text{kg}\) person jump and land rigidly upright on both feet without breaking their legs? Assume that all energy is absorbed by the leg bones in a rigid landing. Express your answer with the appropriate units.
