An iron meteorite melts when it enters the Earth's atmosphere. If its initial temperature, outside of the atmosphere, was -134°C, calculate the minimum velocity the meteorite must have had before it entered Earth's atmosphere. Neglect the gravitational potential energy of the meteorite. (The melting point, specific heat capacity, and latent heat of fusion for iron are, respectively, 1808°C, 450 J/(kg?C°), 289,000 J/kg.)
