My notes 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 = 43.0â° c) for such an event to happen? (use lf = 2.32 104 j/kg and melting point = 327.3â° c.)
