# Problem G. 610. (October 2017)

G. 610. A meteorite of mass $\displaystyle m$, of specific heat capacity $\displaystyle c$ and of specific latent heat of fusion $\displaystyle L$, consists of some material which is extremely good heat conductor. When it reaches the atmosphere of the Earth the temperature of the meteorite is $\displaystyle \Delta T$ below its melting point. In the atmosphere due to friction heat is generated in it at a rate of $\displaystyle P$. How long does it take for the meteorite to be melted totally?

Sorry, the solution is available only in Hungarian. Google translation

Megoldás. Az olvadásig $\displaystyle t=\frac{m(c\Delta T+L)}{P}$ idő telik el.
