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 the a block of ice should ideally be dropped to completely melt if 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/kg. Do you see why the answer doesn't depend on mass?] Express your answer to two significant figures and include the appropriate units. B: Does the answer depend on mass?
