Alead bullet with 30-g of mass traveling at 600 m/s hits a thin iron wall and emerges at a speed of 300 m/s. suppose 50% of the heat generated is absorbed by the bullet, and the initial temperature of the bullet is 20°c. find the final phase and temperature of the lead bullet after the impact. the specific heat of the liquid lead can be assumed to be the same as that of the solid lead.
