A meteor melts when it enters the Earth’s atmosphere. Assuming that the meteor is primarily made of iron and that its initial temperature was −125°C outside of Earth’s atmosphere, calculate the minimum speed it must have had before it entered Earth’s atmosphere. (The specific heat, the melting point, and the latent heat of fusion for iron
are 450 J/kg.°C, 1808°C, and 2.89 x 10^5 J/kg , respectively.)
