Two speeding lead bullets each of mass 5 g and temperature of 20°C collide head on at speeds of 500m/s each. Assuming a perfectly inelastic collision and no loss of energy to the atmospheres, describe the final state of the two bullet system.

1. The final state? Are you assuming no heat was lost

heat= total KE= 2*.06*500^2 * 1/2 joules

temperatue rise: above KE heat= .1*specificheatcapacityLead*deltaTemp
solve for deltatemmp
