It is claimed that if a lead bullet goes fast enough, it can melt completely when it comes to a halt suddenly, and all its kinetic energy is converted into heat via friction. Find the minimum speed of a lead bullet (initial temperature of 30 C) for such an event to happen. Lead has a specific heat capacity of 128 J/(kg C), a melting temperature of 327 C, and a latent heat of fusion of 2.32 x 104 J/kg. O 350 m/s O 215 m/s O 361 m/s O 276 m/s O 247 m/s
