The temperature of a hailstone is 0^(@)C...

The temperature of a hailstone is `0^(@)C` and initially it is at rest. When it falls from a height, `1/60 the` part of it melts. Calculate the height, Ignore the air resistance and assume that the temperature of the surroundings is `0^(@)C`. When it hits the ground, only `1/5 th` of its stored energy is converted into heat.
