John wonders that following:

By how much are each of the blocks deformed in the collision?  What are
they made of and what it increase in temperature of each block?  What was
the time period of the collision and the force profile during the collision.

John, what you want to do is cast the problem within the boundaries of your
paper.  I don't know that I can do that
