SUMMARY
The discussion focuses on calculating the minimum speed of a hailstone at 0 degrees Celsius required to melt upon impact with the Earth's surface. The specific latent heat of fusion of ice is given as 340 kJ/kg. The relevant equations include the kinetic energy formula (Ek = 1/2 mv²) and the heat transfer equation (q = ML). The solution involves equating the kinetic energy of the hailstone to the thermal energy needed to melt the ice.
