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 = 29.0° C) for such an event to happen? (Use Lf = 2.32 104 J/kg and melting point = 327.3° C.)
