Lead has a latent heat of fusion of 2.32 × 104 J/kg, and a specific heat of 128 J/(kg K), and a melting point of 228°C. The ambient temperature is 16°C. A 30-g lead bullet hits a solid surface and comes to a complete stop. What would the velocity of the bullet have to be in order for it to melt completely when it hits the wall, assuming that all its kinetic energy is transformed into heat?
A) 207 m/s
B) 215 m/s
C) 232 m/s
D) 273 m/s
