Thermodynamics question! thanks so much for the help

    1. The problem statement, all variables and given/known data
    a small lump of ice at 0 degrees celsius falls to the earth's surface. when the hailstone hist the surface, all of the kinetic energy of the hailsotne is transferred to thermal energy in the ice. calculate the minimum speed of the hailstone so that it just melts when it hits the surface.

    specific latent heat of fusion of ice is 340kJ/ kg

    2. Relevant equations
    q=mcΔt
    Ek=1/2mv2
    q=ML
    3. The attempt at a solution
    not sure where to start

    What happens when a solid melts? What is the significance of the 'heat of fusion'?

    How does this statement relate to the above questions?
