As part of a forensic test, a 5.0g lead bullet is fired into a fence post. the initial speed of the bullet is 250 m/s. when it comes to res, it is determined that half its kinetic energy had gone into heating the bullet. how much does the bullet's temperature change as a result of being fired into the post?

1/2 *(1/2 m v^20=m*specificheatlead*Deltatemp

1/4 v^2/specificheatlead =Deltatemp
