Latent Heats: A metal has a latent heat of fusion of 2.32 × 104 J/kg, a specific heat of 128 J/kg ? K, and a melting point of 228°C. A 30-g pellet of this metal at 16°C hits a solid wall and comes to a complete stop. What would the speed of the pellet have to be in order for it to melt completely when it hits the wall, assuming that all of its kinetic energy is transformed into heat within the pellet?

A. 207 m/s B. 215 m/s C. 232 m/s D. 273 m/s E. 317 m/s
