If you drop a piece of ice on a hard surface, the energy of impact will melt some of the ice. The higher it drops, the more ice will melt upon impact.
-
Find the height from which a block of ice should ideally be dropped to completely melt it that falls without air drag.[Hint: Equate the joules of gravitational potential energy to the product of the mass of ice and its heat of fusion (in SI units, 335,000 J/kgJ/kg). Do you see why the answer doesn't depend on mass?]
Express your answer to two significant figures and include the appropriate units.
