If it has enough kinetic energy, a molecule at the surface of the Earth can escape the Earth’s gravitation.The acceleration of gravity is 9.8 m/s² , and the Boltzmanns’ constant is 1.38066 × 10⁻²³ J/K. Using energy conservation, determine the minimum kinetic energy needed to escape in terms of the mass of the molecule m, the free-fall acceleration at the surface g, and the radius of the Earth R.
