What is the latent heat of fusion of the cannon ball

Reference no: EM13102192

A cannon ball of mass 10 kg is launched at its melting point with an initial velocity of 100 m/s. If all of its kinetic energy is converted to heat energy, causing the cannon ball to completely melt but not increase in temperature, what is the latent heat of fusion of the cannon ball? The answer ends up being 5 kJ/kg but i'm not sure how to get it.
