Asked by Kirk

A 70g steel bullet moves at 200m/s just before imbedding itself into a thick anchored wood post. If 70% of the initial kinetic energy goes into heating the bullet (steel c = 460 J/kg-C)...how hot does the bullet become if it initially is at 26 degrees Celsius? What would be the bullet's temperature if it had been twice as massive (2 times 70g)?
